I found out about WH's A with a married coworker in December, almost two years after it started. He swore it was over once I found out, but then I found out in February that it had gone underground. I then found out again in July that they were still "friends," and still talked constantly every day. He swears now that he hasn't talked to her since then.
My problem is that I am still incredibly suspicious that the A has gone underground again. WH is getting frustrated by my digging and my refusal to leave the past in the past and work on the future. I understand how important it is to stop dwelling on the past, but until I feel comfortable that the affair has truly ended, I don't know how to stop looking at his phone, his history, etc. throughout our false R he said all the right things, so how do I believe him this time around?
