Sissy.

Have not seen X in a while. He has been busy covering for someone else at work. (This I know to be true thru friends who work with him). However, recently told me that he plans to take a week off in January and is going to a Warmer Climate. Is planning on staying with "my ex-girlfriend who I'm still really good friends with". (Well, that was kind of akward....my response was a noncommital "OK", all the while wondering why he had bothered to tell me that, I didn't ask).
So, if he doesn't want things to continue between us the least he can do is be a man and tell me so.
