You were no fool, and you can hold your head up high.
You were lied to by people you trusted, just like 100% of the people posting in this forum. You spend half your life with this man. You’re supposed to believe him!
IN FACT, it’s almost impossible to believe, right? What kind of person would introduce his AP to his wife? What kind of person would let his AP befriend his wife? What kind of woman would cheat with her friend’s husband? They capitalized on the fact that you didn’t think they were sociopaths. You’re not a fool, and you have nothing to be embarrassed about. You took your high school sweetheart at his word, and you didn’t think he was capable of this level of awfulness.
You have asked us the age-old question, what do I do? You are in a very common situation. You have a WH who will not stop his affair. And yes, he’s still cheating, let’s have none of this "he asked her for space" bullshit. They see each other every day at work. They’re going on a run together. The affair is not over.
There’s no known technique to get someone to stop cheating. If there were, it’d be the pinned post here. The one move that works the best is to set them free and walk away. Seriously, that gets more waywards scrambling to save their marriages than anything.
But it only works when it’s not a tactic. When you realize that you deserve better than to be treated like this. When you realize that you are the prize, and he’s the kind of person who would do all that he did.
You tell him that you will not stay married to someone who is cheating. You tell him that he’s free - if you love someone, set them free, right? He’s free to do whatever he wants with AP, just not as your husband. You tell him that you’re getting out of infidelity, and you’re not waiting around to see if he’s going to get rid of his ‘medal board’ (narcissist much? Are most of the photos in your house pictures of him running marathons and shit?).
Go see that lawyer. Don’t talk to him about your relationship until he proves his affair is over over. Which means going NC with AP, which means one of them has to get a new job.
In the meantime, take care of yourself. Make sure you’re eating and getting exercise. Reach out to friends and family, don’t be ashamed of what he did, your loved ones will support you and you don’t have to do this alone.
I’m sorry you’re hurting MomLife26.
