Should I ask him about this?

I've caught my husband cheating before. I don't know if it was physical, but it was emotional. It was with a coworker. He changed jobs but because it continued even after that, I put an app on his phone that records phone calls, can do surround recording etc. I normally don't pay too much attention to what's going on because I was specifically looking out for one number.

*** He gave me permission to do whatever I needed to do , to make me feel better and not divorce him. So I did, but I just didn't tell him.

So anyway, today I put on the surround recording because I sent him a sexy picture and I wanted to hear if there was any audible reaction to it (silly I know, but I've literally never sent one and I was curious to hear his reaction).

I'm listening to the recording and he was talking to a female coworker about going to get milkshakes together tomorrow morning, he was asking her about things at home, etc, etc. This is EXACTLY how his last emotional affair started. The woman he was talking to was saying how they are house hunting, she needs to find a good area for her kids and school and her support system, etc. Then, my husband OFFERS TO PICK HER FUCKING CHILDREN UP FROM SCHOOL. WHAT THE ACTUAL FUCK.

Then she mentions the area she's currently living in which is a 45 minute drive from our home. He's going to do that for another woman's children everyday? He tells her like 5 times that he'll help her, like she doesn't have his own husband.

And may I add, I wanted to pop in for a cup of coffee with him on Monday and he told me no, he's too busy. But he spent at least 30 minutes talking to her.

What should I do? Confront him? Continue to monitor him and wait?
