(name changer - sorry!)
my story in brief
h and are have been split for 6 months (he left for another woman) there is no hope of a reconciliation.
a few weeks go i get a surprise visit from the man who was the usher at our wedding (he lives in the USA and was over here on business)i have known him for over 11 years. he himself has been separated from him his wife for 18 months (she still wants the marriage to work but he does not want to reconcile - he left her, not sure under what circumstances tbh)
he shows up at my door in a very romantic way - nothing happened that night, he was kind and was enquiring over my welfare since h had left (basically i think he was testing the waters) he then goes home to USA and he has been emailing me since and it is very clear that he has feelings for me - I think i might have feelings for him (but it could be just that i am flattered by the attention?? 
)
if you take out of the equation that he lives the other side of the world 
(there is a chance he could move back to the UK - he is English) is this an inappropriate relationship???
- he is not yet divorced and i know his wife is desperate for them to get back together, i know her and they were family friends before they moved to USA, they have ds)
2)is it wrong for this man and i to start something, albeit very tentative (emails/phone calls) when he was one of h's best friends????
I have not admitted my growing feelings for him as i am not sure what they are tbh, it could be a crush????
