How do you get over cheating?

Abby
Can you really ever get over someone cheating on you? All I can do is sit here and think about it over and over. He was my fiancé. He knew I was pregnant with our rainbow baby. It's the most devastating, betrayal I have ever faced. Could I forgive him and move past it? Is it even worth the effort? I still love him but I don't think I could trust him again...
