I don't think he snapped out of it or ever will tbh. Men naturally stray when they're frustrated and feel down. Who's to say he won't do it again? I actually think it's worse that he admitted to doing threesomes after his first born was born. That wasn't even long ago

I'm willing to bet he talked Bey into getting more kids will bring them closer

and when you think about it, she will be more vulnerable now and emotionally dependent on him. It's just more mess tbh. Children can't save a marriage. He's a calculated manipulator.
