My friend has been dating this guy for less than two weeks, but already they've had sex and oral sex. She is obsessed with him, and whenever we hang out that's all she talks about. Most of the time we hang out she is texting him, and any time another guy is brought up in conversation, she has to compare the two. It makes me feel like a helpless idiot. I have no idea what to think when she says "I wish he was here" whenever we hang out; like I'm sorry I'm here instead?? Mostly I just wish she wouldn't text him when we're doing something together,
but if I bring it up she gets mad.
Personally, I think they're just using each other for sex at this point, but once they break up she'll find another boyfriend pretty quickly. How do I handle this situation rn? I'm not sure how to talk to her about this.

Find better friends or make them jealous

Can't beat umm join umm

I know exactly how you feel. I had such a friend too!
Have you ever told her, that her behaviour is annoying? Maybe she doesn't realize herself how she behaves when she's with you.
Is he her first boyfriend?

Sounds like a teenager problem. How old is your friend?
In case this is her first boyfriend it´s not unusual how she behaves. Just imagine how she feels: She´s indescribable happy. Might see her boyfriend like a charming prince on a white horse or whatever.
Don´t worry, this won´t last long. Just let her get the first problems in her relationship (I don´t want to say that you need to cause these problems...).
After a month or two she´ll awake from her dream and realize that her boyfriend is a normal boy, not better or worser than everyone else. Then she´ll return to her old self.
And in case you´re truly annoyed by her behaviour, stop meeting her for a while or tell her exactly that you´re getting angry and want her to stop right now. Not only to stop texting, also to stop talking non-stop about her boyfriend. Perhaps (like Kyouka said) your friend doesn´t realize how annoying she is, because she´s kind of lost in her feelings for her boyfriend. Only to say "Stop texting!" wouldn´t work in this case!

And about the "sex and oral sex" thing: This also could be a lie. Perhaps you´ve never had a boyfriend before, so she thinks she´s something special now and wants to make you jealous? Don´t know, but it´s a possibility.
Otherwise there is also the possibility of him using her only as a sex toy, as you said yourself. In this case she´ll notice one day and then your problem is solved by itself.

If I had to give you an advice: Just wait and try not getting too mad at her. This might be hard, I know, but it would be sad if your friendship would break off just because of a boy, wouldn´t it?
Give her some time and you´ll see it will get better.
Patience is a virtue, as is said. Be patient for a while.

Then fade away.. look for someone or hanging out with someone. Dont be stuck with her.. and if she ever call's you?? Dont answer walk away. Its a dead flag...

Well, the thing is that we're both going to college in a few months. I'm also afraid that she's going to throw away her time at college by trying to date a lot of guys. So even if her obsession with this guy fades, she'll find another in a matter of days.

this will fade down, her obsession with both her boyfriend, and with dating other people asap. But you could suggest that she goes to a therapist. Becase there might be something serious that she's hiding, and may use other guys to cope with it.

Maybe you should look for another person to hang out with then when she regret what did she just did it depends on you to forgive her or not. If she still the same,if i were you i would go away from her. IF i were you.
