That's great that your husband is giving you the attention you deserve. I hope I get to that point someday.
This really does not answer your question, but something you may want to think about since the OW is still calling because if she is still in his life (even an occasional phone call) it will hurt your reconcilaiton.
I can tell you it is very tough to quit the OW. Not only do you miss the rush of being with but as you and I discussed in another thread OW are only concerned with their life and not the lives they are hurting. The OW will do anything to be in your husbands life.
She will try to be being nice, being mean, making herself look like the victim etc. She will not stop for a while. Your H just needs to break off ALL communication with her. Eventually she will find someone to make a trainwreck out of.
One thing you may want to do since you have already forgiven him is ask him to be honest with you about the battle he is facing letting go of the OW and stopping her advances. If he sees an ally in you, it will strengthen y'alls relationship and give him someone to lean on when he is feeling weak or frustrated.
As far as what else to do to make your marriage work or your situation, I cannot give any advice to that.
