Don't try and use this thread as a dating service, especially not one breath after announcing you've just found out your wife is cheating on you.
Especially with two kids, you need to sort ***out with your wife before attempting to jump straight into any other sort of relationship. For all you know your wife hasn't even cheated on you. Just because she has an profile on the site doesn't mean she's met anyone off it or even intended to. It could just be that she's seeking attention that she's not getting from you. Not saying that's the case, but it could be.
Either way, I'd suggest sorting ***out with your wife before doing anything else. Even before talking about it on a public forum, but it's a bit late for that.
