my husband is an asshole

Sorry for the cursing but I literally can not stand my husband. He cheated on me!! While I was pregnant and has the audacity to sit here and get mad when we have to constantly talk through it!! I'm so done with him. We have been together for so long and everything is down the damn drain. We planned our family and he went out and did that and now treats me like crap. I should have left the day I found out and never looked back! He played me though. Made me think he actually cared. He's a pig and I never thought someone I loved so much could make me hate him so much!! I never met someone more disgusting and manipulative in my life!!
