Until recently exh would text fairly often (we have dc) and offer cups of tea etc at drop off with dc. To the point he was a pain in the arse. I made it clear we were never getting back together (he'd said something to a mutual friend that suggested he thought we might) now in past month he is constantly letting the dc down, not responding to messages, pissing about with arrangements always saying he 'has plans and now he has deactivated his fb account despite previously being on it loads. Aibu to think he is playing some sort of game? Or just trying to be as awkward as possible!
