I'm sorry, but he sounds like a scumbag. No man worth his salt treats a woman that way. Being intoxicated isn't an excuse for anything. The way he was raised isn't an excuse. His friends likewise are no excuse. Dump him asap. He's a danger to you and your unborn child, and it sounds like your dog as well, (which is particularly disgusting on his part). You can do better. You deserve better. Heed the advice of folks like Sparklekitty and Trailmix and contact your local DV center and make a plan. Hugs to you.
