I'll echo the comments already made as well, It's just far far far to soon. You need to sort your head out from your wife leaving before even contemplating another relationship. You need to know where you stand money wise, debt wise etc
If you do like her as well, and it's not a case of you being on the rebound and just wanting someone to be with then talk to her, get to know her better but don't let it manifest itself into anything to serious to quickly. You most defiantly need some time to think things over, everyone will get over bad relationships in different ways and at different speeds but no one can seriously be in the situation for another relationship of any kind so quickly after a major upset.
How did the karaoke go btw?
