If I were in your shoes -- as I will be soon, I believe -- I would be messed up. Despite all the hurting and heartbreak I've gone through, to have my kids tell me about some OM w/ Mommy ... man, I would be messed up.
So kudos for rising above that. For strength.
But it seems to me that your W is eating emotional cake from you when she gets to maintain a strong emotional connection with you.
