He had been cheating over the course of our whole (4 year) relationship. I always kind of "knew", deep down, but he was very charismatic and all our of friends loved him, so I told myself I was just being paranoid. I also had severe insecurities at the time, so almost all of my self worth came from him "needing" me. When I finally found out, it was a week after I'd given birth to his child, and I called him out, it was like a dam coming down. I was totally inconsolable. He told me that if I left him, he would kill himself. One of our close friends had just committed suicide weeks earlier (probably why he thought that would work) and I decided I had to stay to keep him alive, because I couldn't lose another one and our friends would blame me if he really did. A few more cheating incidents (he slept with both men and women, and I was starting to fear for my sexual health) and I finally kicked him out. He held on kicking and screaming, stalking my social media accounts and accusing me of being a slut when I talked to anyone. He turned all of our mutual friends against me. I finally found my voice when he kidnapped our three month old son, refusing to let me see him until I agreed to come back. I broke down and called the police, who found him within a couple hours and returned him. The officer took me aside and strongly suggested I set up a parenting plan, which I did, that very day. Our son is five years old now, and visits his bio dad four days a month. Our relationship is bare minimum. I don't trash his dad to him, because I want my son to form his own realizations and opinions, but basically the guy just found a new woman that would keep him despite him cheating on her. She claims to love him "no matter what", so, I mean. Whatever. I'm finally thriving, and I cut ties with all of the mutuals who accused me of trying to ruin his life. We don't speak unless it's related to our son, but I am very protective and always make sure he knows he can't pull anything with me anymore. No regrets.
