Strong,

Did he go to counseling for this? You said he went to counseling and I just wonder if it was to help him get over this?
Because it seems he has taken this very hard and not lightly at all.

This doesn’t sound like the actions of a chronic cheater. In a way it sounds like he messed up, learned that he doesn’t want that kind of life… that he wants you and realizes he could have lost you and wants to show you and make it up to you.

I am thinking that since things are so good that you could either keep trying to get stronger with him and see if more trust develops or just continue seeing him and maybe see others too (if you want to) just to make sure you are on the right path.

If seeing others turns your stomach then maybe you will just have to forgive him and decide to trust again.

I guess you and only you know deep inside yourself what is right.
