User post: Am I just not meant to have friends?

So it's always been pretty easy for me to meet new people and make new friends, but keeping them is another thing. What happens is i'll meet someone and be really excited about the person and hang out/talk to this new person everyday for about 2-5 months straight then all of a sudden things change. I open up and let them in very quickly, but once they are all the way in and i'm comfortable I shut down and push them away. Then I get in a rut of not wanting to talk to anyone for about 3 months, no matter who it is. Sometimes I wonder "Am I just not meant to have friends?" I mean I have friends but not close "best friends". I know that it's me who has the problem and not everyone else, but I really don't understand why I do this. I don't know I guess it's just in every movie a girl has a group of close friends and I don't really have that. Maybe I just don't want people knowing the real me. It's almost like i'm scared but I don't know what of. It's also not like anything really goes bad, I just stop talking to them and I don't go to places where I know they'll be. Is it just me or are there other people out there with the same problem?
