On Sunday, my Ds and I picked up my W and we first went to Mass together. In the whole church full of happy families, my W didn't even crack a smile. She seemed (for lack of a better term) ashamed or guilty. She didn't even go up for Communion.
I'm assuming you guys are Catholic. Maybe suggest to your W that she go to confession. It truly is cathartic, especially when dealing with something you feel guilty about. Receiving the Lord's forgiveness can help people forgive themselves.
It's a tough thing to do, as I think most Catholics don't take advantage of it out of shame or embarrassment (believe me I know - I went over 20 years between confessions before I went last year, now I go pretty regularly). Once you get it out of the way, it feels great, and much easier to do on a regular basis.
