Honestly go. I have been there. I realized it to late (married him two kids) only to find out in the 5 years together, two and half of them he was stepping out and slept with 15 other women. He had the dating apps, chat apps, etc. Our relationship wasn't always peaches and cream but when I would find out about it, confront him, he would beg for forgiveness but I never really could get over it. I stayed because I loved the man I met. I was hoping he could keep his word to me and not do it again but than it would happen again a few months later. I could truly never forgive or forget. I lost all trust in him when it came to us, I lost respect for him, and in the end I started to even hate myself for staying. If he makes you feel any less of yourself thanhe is not the one.
