To me, it sounds like he is trying to bait you. He’s not behaving like someone in an affair, he’s behaving like someone who likes to get a rise out of you. Could he be really, really insecure at heart, and using these not-so-suble maneuvers to feel as if you loved him? As in, "she’s jealous so she must care"?
That thing about the wedding ring a few days ago … HE noticed that YOU were not wearing it. He talks to the lawyer he knows you’re worried about INFRONT of you. He brings up songs from a past he knows you’re worried about.
So, he’s either a very insensitive (not to say cruel) man who enjoys seeing you suffer, or he's a immature little boy trying to get your attention.
