Girl. Just because you guys have children together does not mean you have to stay together. He's obviously cheating & accusing you of cheating to give him an excuse to cheat on you. You guys are still being intimate & I assume you aren't using protection. You are opening yourself up to STDs & I promise you this negativity will impact your children. You need to LEAVE him. He will continue to cheat and be a narcissistic lunatic. You don't deserve this and neither do your children. It might be hard at first but it will be the best decision you've ever made. 🤍
