H left in February and pursued a relationship with his mistress. He comes over to spend time with our 2 year old son, and during nap times wants to be intimate. I even caught him tearing up while we were in each others arms. Another time he wanted to lie down next to me in our son's room while he was sleeping, just to hold me and look at our son. I said that our son was perfect, and he said, "Just like his mother."

However, I hear from his family that he seems extremely happy with the OW and they are taking business trips, vacations, and planning to live together. He hired her to work for him after having an EA with her (before he had the PA and before he left), so now they are side by side 24/7 and don't seem to be getting sick of each other.

Not sure if I am doing the right thing by allowing the intimacy. Is it helping or hurting my cause? He even says he loves "us" as he is leaving, or when ending a phone call. This should be a good sign, but has been going on for several months now and does not seem to be affecting his "other" life at all.

Should I continue and be patient? Or am I being used?
