Kind of a wwyd but also need some help to keep my head straight.
My partner of two years is treating me like shit. Argument after argument it's wearing me down. Every time I say I'm upset about something he doesn't want to hear it then turns it all round on me. The latest is this...
Yesterday I bumped into him on the start of his lunch break at work, instead of stopping to talk for a minute he just says he in a rush scurried off. It left me feeling a bit miffed that he couldn't stop for even a minute to have a chat with me, ask how the baby is (she was with me) or even ask how I am (I'm dosed up on painkillers and antibiotics for my ear, been really poorly for a few days now). I think that after all the bickering lately it upset me that he couldn't take one minute of his lunch break to actually acknowledge me. Then went on his break, I half expected a text message just explaining that he was in a rush etc etc but nothing. His break was half an hour long. So I sent a message that was lighthearted but showed that I felt a bit 
about it and he went off on one. Now apparently he does so much for me, treats me so well etc even said "if I'm that bad then why you still with me eh?" I replied that given the way he's treating me I don't even know. He's clung to that with all his might and now I am to blame for the whole thing. He got home from work yesterday and went straight upstairs to the bedroom, shut the door and didn't even speak to me, didn't come down, nothing. This morning he's not even looked at me, not spoke a word, wouldn't even be in the same room as me. When I left his afternoon to go out I said goodbye and he said nothing, so I asked if he's really going to just ignore me and he viciously said "I said cya!" Again wouldn't even look at me. Since that I messaged him saying that I can't believe this is he treatment I get for saying that I was a bit upset that I basically got ignored by him at work and he's going on and on again about how he treats me so well, is so good to me etc etc. He tried to call my bluff telling me that if I'm so unhappy to go and find a man that will treat me better since he treats me like shit. So I said I'm not prepared to spend another night being made to feel inferior and not even good enough to be in the same room as and it that I refuse to live like that, got home and he's ignoring me again.
Fucking had enough I really have. I'm on the brink of just ending it but I don't know how. We had a bad break up about a year ago and he has this way of making me feel like I'm the worst person in the world, it's my fault and the last time he literally reduced me to bits, I had to go to my mums because I felt like I was about to fall apart. I just don't feel ready to face those feelings again. That's what's holding me back.
Am I right in thinking that regardless of how he feels I've done something wrong, it's completely out of order to just disappear to the bedroom and not be in the same room as me? He will say it's my fault for how I was yesterday. He will convince me that it is my fault. I can't face it. I have no idea how I've become so weak.
So, am I in the wrong? And wwyd?
