In short. I had a fling, very short with a bloke I knew. It wasn't there. The chemistry.
But we got on great as friends. Stayed friends for 4/5 years with no sex but then a drunken fumble.
Was massively akward, didn't talk for mths. He then got a gf & we went back to friends, never to talk about the drunken fumble.
Fast 4ward 2 years and his gf now doesn't want/like him having anything to do with me 
Then 6mths later he confesses his undying love (to me)
Can this ever go bk to just friends?? Shall I try and be friends? Shall I cut contact??
What about his gf?
