Recently been trying to get rid of a sociopath I’ve been dating on and off (no surprise there) for 6 years. Situation is: I took him back about 1.5 yr ago after being apart for 9 months. We moved in together and he brought his teenaged son and I have a young daughter. One big happy family at first but very soon after the lying, cheating and abuse started all over again. I’ve caught him cheating and lying for the last time and now am lying & manipulating him to get him out of my house. (Long story, but it’s working) The problem now is my attachment to his son and my guilt for lying to him also just to get the abuser away from me. I realize very soon once all of this is over I will have to go “no contact” and he will be on his own to deal with his dad completely oblivious of what this disorder is and how he himself has been affected by it. I know I’m not his biological mom, we’ve only lived in the same household for 1.5 years but I feel like I’m abandoning him.  I wish there was something I could say to him that might encourage him to seek professional help. At some point someone has to try and break this cycle don’t they? I realize it’s too dangerous for me to get in the middle and he certainly can’t stay with me. I’m sticking to my plan, but I can’t help feeling such pain in my heart for him. I hate my ex even more knowing that all his son is to him is another tool for manipulating me and the fact that I’m writing about it proves it worked. Any support on this topic is greatly appreciated and it’s helpful to hear other stories and know I’m not alone.
