To me it sounds like the typical MLC behavior. Hiding in a cave, they come out for a moment, and then pop back into the cave. Withdrawal is their safety mechanism. She can't come fully out of the cave yet. Of course, she is suffering in the apt. So if he lets her stay on her own, it may give her more of these need to cuddle nights. It may help draw her out of the cave.
OM is such a user. Probably he just wanted to see if he could get it up with another woman, since he already knew he had problems. That is very typical behavior on his part.
