I don't really know how to explain this and it probably seems trivial to most people but it isn't for me, so...
Basically, I'm not a very social person. I have one best friend, a couple of other friends and a few 'lesser' friends ( Horrible thing to call them, but I'm not really that close to them, there more like friendly acquaintances). I've always been a bit of a clingy person, there was a time when my best friend was my only friend and I rarely left her side in school. When she started hanging out with other people I felt left out and a bit angry if I'm honest, but if she didn't make new friends, chances are I wouldn't have talked to them and befriended them too. Currently, I've started to make new friends and I've been hanging out with them instead of her, I still make time for her though. Before this year I rarely met friends out side of a school, I'm quite anti-social, I'll talk to people but I don't go out shopping with people, I rarely leave the house. This year, I've started staying over at friends' houses, just not my bestie's. Before now oir friendship was rather one-sided on my part, I just kinda followed her around and she put up with me XD, but recently she's been hanging out with me alone and seems to be enjoying my company more. I can't help but think I might be being hypocritical by hanging out with my other friends and I'm afraid she's become scared of losing me. I don't really know what to do. My new friends have interests closer to mine but my bestie has been my friend since primary school. What should I do, if anyhing?

your new friends have interests similar to you, witch makes it easier to hang out with them. but your have so many memories from your best friend. this is not as hard as you think. invite your best friend your new friends. if your other friends feel great while hanging around with you then why wouldn't your best friend feel the same? they all love you right? and this is what i call making a squad xD my squad is 2 girls+6 guys(including my boyfriend) and a few other friends of mine that i hang out with when we both find ourselves alone. but the people i really hang out with the most is the 2 girls. but at lunch we all gather at a table and eat. we a lot of people and we enjoy each others company. and the funny thing is that i befriended 1 guy and i was immediately draged into his group. then i found a girl in my class and we became really good friends, then later on i found another girl and we started to hang out a lot. now i got a boyfriend and the friendship we had before has been stronger. introduce your best friend to your other friends. i think that a good idea

You don't have to choose between them. Why? I hang out with about 4 social groups and I never favor the other. I go to the ones that I feel like and they know me as the guy with other friends so I'm fine.. Try to mix that group of 2 into 1 and see if your bestie wants hang out with you and your new friends.. Idk..

you think so? hm.. you might have a point there.. hey Delphi. could you give us a more detailed description of those people?

A more detailed description? Um... Well my new friends come from all over the place, other years and other groups and stuff. They're pretty much all into anime, something my bestie never found herself liking. I have other friends who are into other things too though. My bestie is into gaming like me though. What else? ...
