I knew a guy about 10 years ago. Casual relationship, got on great, amazing sex (nothing has compared). We have bumped into each other once or twice over the years and sent the odd hi how are you text. Both married / kids, although I'm now separated. Saw each other in the street a few weeks ago and started texting. It has got a bit carried away with talking about past encounters so I put the brakes on. He now tells me he wishes we'd properly dated and that he was just young and silly at the time. I said he can let me know if he is single again as no way would I consider seeing a married man. Do you think he is just using me or is there possibly something still there between us? I refuse to be someone's leftovers but I have always thought about him on and off over the years and wondered what if.
