I lost a good woman. Never give them an ultimatum

I don't usually post here but I thought I'd share this story and indirectly ask for some advice. I'm not a total loser or a chad. I'm a high-value man with a good job, good health, and good looks. Looks fade and health isn't guaranteed, though.<br><br>My wife and I met on a dating app in 2018 and we got married in 2019. We've been happy for the most part, but I never got over the fact that she had slept with over 20 men. She was "promiscuous" in her younger years.<br><br>Well, I just found out she had an abortion in 2016 and she didn't tell me. I'm fucking livid. I don't think I can ever get over this. We have 2 daughters together and I was planning to have more children with her. I would never want to have kids with another woman.<br><br>I gave her an ultimatum. I told her I want a paternity test for both of our girls and that I want her to see a therapist. If she doesn't comply, I'm leaving.<br><br>She's freaked out. Like, literally crazy. I don't recognize her. I think I might end up leaving anyway. I'm just so fucking mad.<br><br>I don't know what to do. I'm heartbroken. I really thought she was the one.
