Looking at your phone records seems fairly benign to me. Confronting your H is OK too, I think. To let him know what is acceptable or not to you. The fact that he was sorry about it says that all his talk about filing D is ... at least he hasn't completely decided. Which is good.
But here's what you have to do: decide what you're going to do if he resumes. Or if you see some other evidence that he's cheating on you. You can confront him again, sure. But then what? If he crosses that boundary, what are YOU going to do? You can't force him to stop seeing other women. What can YOU do that is within your control? I'm not saying it will come to that -- but you have to think about it, so that you don't just make empty threats. More importantly, you have to make this into something that YOU are controlling about YOURSELF, rather than you trying to control his behavior.
Simple, but difficult.
And all easy for me to say as an armchair advisor.... I know this stuff is really hard to live through.
Be an excellent person, Z.
