Advice Needed- setting boundaries

[Sam3]

I'm very torn. I want to believe that he's telling truth. (But believe none of what they say) I gave him the opportunity to tell me for 3 weeks in a row. That I saw the texts coming in, before I told him I knew about her. Then he told me that he told her last week that he was ending their "friendship."

Because, I told him that I had personal boundaries and texting her 15 times a day from our family home was disrespectful. I told him to do what he wants down there, that I have no control over him. But, not in front of our children & me. I told him I wanted proof by checking phone bill that he wasn't doing it in the weekends he is here.

He said he felt like I was pressuring him to work things in marriage out. Or else i was going to restrict when he could see the kids. I told him "No. But you aren't going to be texting this woman while sitting on our couch."

But, then to see he goes and buys another cell phone. It's crazy the effort he is going thru to keep this going. Seems like there is more there than just a friend he talks to.

Oh, he also locks his phone & iPad in his car at night along with his keys. And uses the door code to open the car. Which he knows I don't know code.
