Ok so I have been dating for over six months, but I dont know what to do anymore...

My bf told me about how a “little while ago” (I do not know how long ago exactly) he lost feelings for me and wanted to be with this other girl, whom he had had feelings for before me. He also went to a movie I wanted to see with him, but he went with her, and I feel like that counts as cheating. Am I wrong?? He also started working waaay more and I haven't seen him in two weeks. I feel like he’s avoiding me and I think I’ve lost feelings for him now, but every time he does pay attention to me I think I like him again, then he stops and I stop.

Ladies

What should I do???????????????
