I'm sorry your boyfriend is acting this way. Have you sat down and expressed all this to him? I know when my boyfriend acted this way it is because he was feeling miserable as well. Men exhibit these things differently than woman, usually they don't talk about it and it can come out as anger or indifference.
I think you two should sit down and talk about how he's making you feel and hopefully he will understand and open up to you. Feel better, love!
