Not All Change Is Good.

He was perfect when I first met him and I loved him so much. That is, until we married. He changed. I know people change and I can't expect him to stay the same but his change wasn't for the better.  I feel like we are just room mates now. I haven't been happy for months. At first I thought it was just a phase all couples go through but it never went away. I tried talking to him about it but all he would say is: its your problem that you feel that way not mine. I have tried to work things out with him and reconnect with him but I feel like I am the one doing all the work. I don't feel like he cares or appreciates me anymore. I know I have snapped at him and I know its not all his fault but I'm trying so hard to make this work and it seems like he doesn't care. I want to take a break from him but at the same time I'm scared of being alone. I have separation issues from childhood and I get anxiety attacks. I feel like that is holding me back and not letting me get the break I need but at the same time I want to work this out without having to do so. He is just a completely different man now. Instead of bringing me up he puts me down and makes me feel so worthless. I don't know what to do anymore.
