I have a girlfriend since a while back. Everything is going well and we have fun together. We like the same movies and we bowl together, I always have a good time when we hang out.
But my friends make fun of her. She’s beautiful in my eyes but they always find something to pick on. Her weight, her life, her clothes.

I feel like my friends want me to break up with her, and I have actually considered it a few times because, it’s so difficult to listen to their comments about her. It makes me feel ashamed that, I have a girlfriend my mates make fun of. I am the only guy in my group that they do this to too.
I even become mean to her because of this and, it makes me feel bad when I treat her like this. She doesn’t deserve it.

Can anyone give me some advice on the matter?

Man, i think you should discuss this with her, and explain her what happened between you and your friends, and also if they just make fun of you because of a girl that you like i don't really think they are your friends, i mean they should respect your choice an keep it to themselves or just as long as you are not with them. Also if everything just resumes to weight, that can be changed, ether get more ore lose some not a big deal, but i don't think you should be mean to her because of this, just be open to her... Also it all come own on who will you chose, your friends or your girlfriend, there's no shame if you chose your friends, it just means it wasn't thee right person for you or that you are not ready for a relation, just think about it and talk to her...

I'm sure it can be solved out without hurting anyone ego or feelings

Personal opinion I think if you got a good time with her and care for her you shouldn't break up, but maybe try to talk with your friends to not make fun of her.

I think you should try to find new friends. They have no right to make fun of your girlfriend and if you really care about her the way you described, the fault is on your friends behalf. It's your relationship and they shouldn't get in your way.

I agree with 134340. I think you should find new friends. They are obviously jealous of the fact that you have a girlfriend and want you to break up with her. These are not your true friends and I would stay away from such people.

thrash mates you have there, do dafuq you want and dont let fucking hive minds manipulate you, lol friends who shittest wtf even thats shit what cunts do not man or friends,

like 4. said try to get new pals or stay to yourself ( but try to improve yourself and dont fall into profound emptiness, you dont wanna be at such low trus me ) there will always be a societal hierarchy that wants you to be this and that, but fucking friends? hell no, ignore those shits that are your friends, they seem unhealthy

You should not feel ashamed of having a girlfriend you are proud of. Your friends, or so-called "friends," are nit-picking on her weight, style, etc., but if you think she is beautiful the way she is, then that should be final.

Also, find friends that actually accept your relationship. Real friends would be there to tell you if your relationship is unhealthy, but only if the reasons are actually legitimate, which shows that they actually care for your well-being. From what I've read from your post, the current evaluations from your friends about your girlfriend should not be taken with any real weight.

Thank you all for your support and encouraging words.

I had a talk with my girlfriend about what my friends say and, she got very sad and upset.
I told her I will take some time off from my friends because, as a few of you pointed out, they are not being good friends, really.

I miss hanging out with them though but, I feel like I really want to give my relationship a chance because, maybe I will never find someone like her again.

YES. do not give up on her. your friends are probably jealous :")
r they single ahaha
or do their girlfriends not satisfy them that much.

honestly idk, but usually when someone's in a dark mood and sees someone they're close with happy, they usually lash out at them first.
but then again, they might just want the best for you.

but you don't know. thats why i suggest you to all to them and pry the reason why they do those stuff outta them. you can get nowhere without listening to their reasons.

if their reason actually sounds like a balladic one, you can take a break off them yes?

but i suggest you to talk to them first before actions are taken, to not cause any hash misunderstandings.

Ahhhh I like to make this a short Managua story XD BUT MY DRAWING SUCKS
I like every one who encouraged him :D generally nice persons

I know this is somewhat old and you already got a lot of answers, but Im going to tell you to stay with her and work through the relationship.
If she and you are enjoying each others company and are nice to each other, then why end the relationship?
Just stay away from your friends for a time being and make better friends. Or if you want to hang out with your old ones, tell them that you dont appreciate their opinions and that they should stop interfering with your relationship.
Set boundaries with them, since they seem to not know their own.

Best wishes to your relationship with your girlfriend and new/old friends.

At the end of the day,what matters is how YOU see her. You're the one in a relationship with her, not your friends.

That’s terrible of your friends. If they want you to break up with her, they should talk to you and tell you why, but ultimately it’s your relationship and your decision to make, and if they are good friends, they will respect that. Instead of treating her badly on top of their bullying, you can turn your frustrations back at them for being assholes. Or better yet, let them know that if they have a problem with her, they can talk to you DIRECTLY about it and if they keep disrespecting your girlfriend and your right to date whoever you want to, you will avoid them entirely - and if they keep doing so, avoid them because they clearly don’t care about your concerns.

Do you love her?

If not, break up no matter what.

If you do?

Break them all, they deserve it for saying what they've said.

When start making fun and poking fun at your girlfriend as well, this is signaling to your friends that this is OKAY to do. This is not okay, not to you at least. Sit down with your friends and have a serious discussion, this might be hard for you to do but if its important to you then muster through it.

As to the decision as to whether to break up with her or not, the decision is yours. HOWEVER, DO NOT ACT like you're doing her a favor. "I'm breaking up with her because she doesn't deserve this/me", "This is better for her this way" or whatever it is. If you really cared about what she deserves then you'd give it to her yourself.

Be honest with yourself and her, you at least owe her that much.
