I was seeing this guy I work with for a few weeks, everything was going well. I made it clear I didn’t want a relationship and just wanted to mess about a bit. Well he was very much on the same page as me until he wasn’t. Out of no where he changed and said he didn’t think it was a good idea bla bla bla. Well now I’ve come to find out he’s back with the ex girlfriend but he continues to sort of flirt with me at work, he’s stopped messaging but I still feel that tension between us and he keeps giving mixed signals. What do I doooooo??
