I have a very strange insecurity… I need someone's opinion on it.?

[Emma]

Okay so Im 22 and at university. I have had guys that I have been interested in and vice versa. BUT I have a very strange insecurity.
So say for example that this guy adds me on Facebook and I go through his pictures and I see him with loads of friends - having a great time going out etc. it makes me feel uncomfortable towards him and I think it's because I don't really have a solid group of friends that I myself hang out with. Instead I have friendships that are more 'one to one' - I have singular relationships rather then communal ones if you get what I mean. I have my flat mates and stuff and we are a group but we aren't really a 'solid' group. Also I don't really have many guy friends I'm more of a girl friend person and so when I see pictures of a guy that I like, having this group of friends it makes me feel insecure because I think he will think Im a loser. << Thats the main problem - I think he will think Im a loser because Im not having fun in a group with lots of friends like he is and as a result I end up thinking he is better then me!

Its a very strange insecurity. Someone help
Its not that I have no friends, I do… but it's just that I have close, intimate, one to one friendships rather then a big group.
thank you so much for the supportive answers - they are making me cry! With relief! … I really appreciate it.
