There have been references over the months but not specifics and I could never tell if he was f*cking with me (he was in a way)...
But yesterday he was stressed out because supposedly someone came up to him while he was with the kids and asked him about his "girlfriend." That really go to him and he wanted to make sure I would tell him if the kids said anything. It was the catalyst for bringing it out. But, really, he outed himself.
