He films and keeps everything painful to me?

When my boyfriend and I fight sometimes I get so heartbroken and upset I cry hysterically and should out things like, “you don’t care” or “I am miserable” and typically cry myself to sleep. I went threw our video cameral and found that instead of comforting me he has been filming my pain? I also found the notes I write him when I am upset saved on his computer and one I hand wrote in his wallet? The one in his wallet said what I have to live for if I have no love in my life. I was upset that day at a family tragedy and he was selfish and did not care or want to hear it so I wrote that to him before I went to bed last year! Why is he keeping these things? Why would someone film someone else’s heartache and not lend a shoulder instead? I don’t understand it! Has anyone else experiences this kind of act?
