Well the wife is 45 in August and I am 55, so there's 10 years between us which has never really been a problem, that I've noticed. We don't have any kids, which is a bit of an emotional subject, but happy to discuss.
We have been together since 2002, so that's 19 years and have been married for 11. We have known each other for 21 years in all, but it wasn't until 2001 that we started to get to know each other really well.
She had an affair with me prior to leaving her boyfriend and left him in the same manner as she's left me now and 10 years previously (2011).
So that's a very brief history.
