DH and I have been having an ongoing issue with a woman he knows. She's eight years older than both of us (we are 33) and recently separated. We have two mutual DC, 8 and 6, and he's stepdad to my older DC, 14 and 16. Him and this woman have known each other casually for about twenty years but in that time she's had two husbands and three kids. Six months ago she and her husband split up after she had an affair with another guy locally. They've been doing a lot of texting in the last while. I checked his phone and one of my older DC saw them together sitting in his car. DH said when I asked him to stop that if I asked him to stop texting her that he isn't sleeping with her but that if was a choice between speaking to her or losing me he'd rather pick her and we might as well call
It quits.
He goes out at night, supposedly to work. My older son recently said he thought they were together and last week I told my sisters I thought there was something going on. They started following him and found them and found them parked together in a car. They weren't actually doing anything, just sitting. He says they're not having an affair, apparently they're just talking. I don't know what to believe at this point, I'm totally lost. I can't believe he'd do this, we used to be so strong.
