All honesty & speaking from experience, she might like the kind of person you are, but she may not be all that physically attracted to you. Looks don't matter, but there does have to be some type of attraction. She might also have that fear of being alone, so she's waiting for someone else to come along before she really does break up with you. In the mean time she's trying to pick fights to make it all the easier for the 2 of you to split. I don't know the whole story, that's just my opinion. Hope it helps you out.
