So tired of it...

So glad I found this group... I have had so much on my mind lately. My SO is just completely being an ass. He called me fat the other day and said if he could have sex with other girls. I said absolutely not. And he said oh thats right because you cant handle it and you are just way too much of a jealous person. Like who asks their pregnant wife to have an open marriage? I have never felt so disrespected in my life. I dont ever want to be around him. He recently just locked him phone and Im all for privacy but after u mention you want an open marriage then you lock your phone what am I suppose to think... I am so fed up to the point where i just want to pack my things and leave.... I need your advice ladies because i dont deserve this. And neither does my child.
