If he's married with a kid and entertaining the idea of leaving and talking to another woman AND you're going along with it. You deserve each other.

It's not a good long term situation. If things are bad enough that they've seperated it doesn't matter if they're only staying together for the kid. They're only delaying the inevitable and making things messier in the interim. If you stay with him you could get dragged into their mess and become a sticking point.
