I had a thing (not serious, but still got involved much deeper than I should have done) with a guy, who I knew from my past. I was suffering serious marriage breakdown (ex H done for posession of indecent images of children), all devastating. This guy from my past (who lives abroad) got in touch (pure coincidence - there had been no contact for 18 years) via LinkedIn last summer, when I was alone and very vulnerable and open to being desired, given what my exH had done.
Anyway, it was going well: he come over to see me, we had amazing time, Then he disappeared, reappeared, disappeared etc. Totally twat - but I wasn't strong. He asked me to go and visit him in the summer - jumped at the chance. Two weeks later he's back with an ex... I mean - you could have predicted that 
Trouble is, I forked out for the airfare and he said he would pay it back. I know it's my own fault for allowing myself to be treated this way (after all, he did the same 18 years ago...), but that's not what I'm asking.
What I'd like to know is: Would you persue it (it's less than £200, but still...)? I'm tearing myself up inside with anger and fury at being out of pocket, especially when he knew my situation (single parent, two kids - not a lot of money). Or should I let it go and move on? Ladies - what would you do??? Please advise!!
PS: Have been reading the No Contact Rule to help get over this - it's brilliant!
