The girl who is incapable of love.

I started talking to this girl around a year ago, we’ve been on and off for most this time. I’ve been in other relationships, but I’ve ended up talking with her time and time again. Usually it’ll be her out of the blue texting me. I’ll reply after a while and we’ll talk. We have nice conversations, she’s revealed a lot of things about herself. She just randomly disappears though and it’s confusing. My heart hurts, she never tells me how she feels and confuses me. One min she tells me all the things that she loves about me and the next she tells me of all her inadequacies. I love her for who she is and she’s a pretty girl, even my female friends think so. She’ll always say stuff about how she doesn’t deserve someone like me, how she doesn’t understand how someone so amazing loves her. Then she’ll ghost me for 2 weeks-2months. I’ll be sad and get over it, but then she’ll come back! I don’t understand, her signals make no sense and my heart can’t take much more, if she doesn’t want anything I just want closure.
