Not wanting to be on this boat........

[Buffet]

Birthday dinner tonight at her parents house and that went ok. However she made it very clear that she did not want to talk to me or have fun with me at all. Went out of her way to not be near me or around me. What is confusing is she was very adament that I go over there tonight as I did not even want to attend b/c I do not feel comfortable over there anymore with everything that is going on. On the drive home she started to angrily cry and say that I am ruining things and she wants to be left alone?
She says that she wants to be left alone, however she does not want me to leave, she also does not want to talk, nor does she want to split up at this point?? I am very confused....
Also, she says that I am selfish--how do you make things more about her and not be about you? I know that I am all over the place in this post but could use some real help.
