I've posted previously when I found out DP was cheating. (I'm pregnant, we had plans for the future etc..)
At the time because I was so emotional I didn't want to speak through any details with him. Now I still feel completely terrible but feel like I want to talk to him about it, for closure.
I think he still thinks he's 'gotten away with it' by writing it off as my paranoia. (As he has been doing for several months, sending me on guilt trips, making me feel awful for having suspicions which were completely correct!)
