According to my husband he’s been unhappy for the last 3 years the only thing that has changed in the last 3 years were we had kids back to back we been married for 5 years but together for 14years

So his been cheating on me since thanksgiving I found out the day after Christmas, he’s cheating before just it was before we got married and he was talking to women online

So he’s keeps saying he’s in a committed relationship with her and she not going anywhere that they are soul mates 🙄.....we had sex yesterday it just happened it was easy and comfortable now he’s saying I Manipulated him and used him and all that bullshit and it was clearly the other way around but nonetheless it happened and now he saying he’s not gonna ever sleep with me again and he’s not gonna tell her what happened he’s a habitual cheater he’s already ruined so many lives by what he did now he’s going to ruin this one’s life as much as I don’t like that woman she doesn’t deserve him lying to her and promising her things that he cannot accomplish

I’m not looking for any judgment I am not gonna get back together with him we already getting a divorce but I need to know whether I should tell her or not because she’s only two months into this and he’s already cheated on her with me

Update: yes she knew he was married I met her and hung out with her during the affair my husband wanted me to be friends with her.....
