So I was seeing this girl for a while we never made it serious but it felt like it was getting that way.. then out of the blue she decides that we should stop what we are doing because its heading down that way but I had fallen for her an I had told her all this so she suggests "we stay friends" which is the worst feeling ever! But I decided that I can't be just friends when it drives me crazy just thinking about you so I needed to forget her... I tried to do this but she texts me when she is drunk or just horny or lonely an being hopelessly in love I always go there hoping... but the next day she fully regrets it an then makes me feel real bad about it. When I do go around she says its ****ed up what we are doing so I ask if she wants me to leave but she says no! She also says that I'm everything she wants in a girlfriend she just doesn't want it!what does this mean .
Should I keep trying or give up on her?
