Real girl problems!!

My girlfriend confuses the hell out of me!!! We have been going out for more than a month now but sometimes I feel like I`m with a total stranger.At first(before we were a couple) we used to talk about everything but ever since she told me that she was falling for me and I admitted that I felt the same, we don`t seem to have much more to talk about. She used to call me but these days I do all the calling. When I send messages to here phone she won`t reply. When I ask here what is wrong she won`t tell me...even if I persist in asking her.
The other thing that bothers me is when we kiss. She kisses me for a few seconds and then pulls away, even our first kiss was like this even though she initiated it. But one thing that kinda got me worried is the way she`s always complaining about the way she looks even though she always likes telling me about all the guys that wanted to date her. Sometimes she doesnt like me looking at her because she says she`s shy. I`m crazy about her but I don`t think she believes me. A couple of days ago I told her that I loved her and she as usual did not show emotion. Yesterday out of the blue she said that she did not love me she cared about me but was thinking of breaking up with me.If anyone is reading this please help me out because I don`t know what do do.

Wow you must really be into to this girl if you are going to allow someone to walk all over you. to be honest it sounds like she just wants to be friends if she is telling you how insecure she is about her body and doesnt want you looking at her that way. Then telling you how all these other guys want her so bad. Please save yourself some diginty and if you really love her you will let her go. She probally loves you but she just isnt In love with you. It doesnt have to be a bad break up just keep it cool and suggest just being friends it will take the pressure off of both of you. making the relationship a lot more flexible. maybe you might find something to talk about in the time you spend away from eachother. I hope to have helped.
