Will he leave his wife?

Ok my guy is married!!! HOLD ON AND LISTEN BEFORE YOU JUDGE!!! Ok so here’s the story. We’ve been seeing eachother for 3 months, he’s my step dad’s nephew, his whole family knows and is very supportive of us!!! His wife knows and we’ve talked she’s glad he’s found someone else, she’s been messing around on him for two years. I’m the first person he’s been with. But he’s still living in the house now lately I’ve really been on him to leave the how, he says he’s gotta figure out what to do with the kids, cause he’s the one that always watches them. Because the wife works nights and when she’s not working she’s out. The only mother I know that NEVER spends anytime with her kids. But anyways, I first told him he has until Oct. 18th to move out then I told him he has until the 1st of Oct. Now yesterday I told him everything on how I feel and where I see this going and how it’s unfair how he’s been putting me through this, and how he says he loves me and wants to be with me and then puts me through this. Then he started talking about the kids and blah blah…I told him to stop using the kids as an excuse. I told him he needs to move out, if not for me, for himself she’s been cheating on him for two years and he’s still there I asked him how pathetic that makes him look. But do you think he’ll come through??? He has until this Friday to have this talk he’s saying he’s going to have with his wife, or it’s over…Do you think he’ll come through???
