It's all about Forgiving others, that have done you wrong...seems like the Holy Spirit is working with you, that's why you feel the way you do...

Pray about it, pray for them both to and for their children, ask for yourself help with closure...you were blindsided pretty good, sounds like.

Christians are supposed to Love the Sinner, but hate there Sins...at the end of the day... That's hard to do by yourself so many hurt feelings one must deal with, but calling upon the name of Jesus helps with matters of the heart.
