How to cope

How do you guys work through, cope, and move on from being hurt by your significant other? He has hurt my heart pretty bad. I don't want to leave him, I'm 28 weeks pregnant, I do love him, and I don't want to lose him, but I am not looking at him the same right now. He's made me feel betrayed, and has hurt me to where I don't even want to look at him right now. I just need to work through all these emotions and try to get through it. What are some good things to do that will help? My coping mechanisms are not healthy at all so I can't and won't rely on them. I don't want my baby to hurt because I am. But I also need a way to get through this and get these things out.
