I was surprised when he said that no one had used him for good or bad since his wife left him. The implication was definitely that he got it on with Mrs. Sota. So what was all that anyway?"

I think that Mrs. Sota checked to see if anyone was looking because she was still, on some level, protecting her husband's reputation, looking out for some of his possible associates, etc. I think Angel would've picked up on that, no matter if other signals were present, and treated her kindly but not engaged in a sexual act at that point. He was really focused on looking for answers to the murders.
