I was in a relationship with a sociopath. I somewhat she is the reason my psychosis sparked. After I broke up with her I was in a deep depression for some time. Then I a high unlike anything I've ever felt. I was a free rolling man and I loved it. Then came the break and the journey back from it. Psychopaths and sociopaths are not good people to be around. You can't change them, you can't make them feel. The way their brains are, it's their own burden. Much like a mental illness, they will keep using people to get what they want and never have true connection with people. You still being in this relationship resembles the false hope I once had that one day their would be no more downs. That is a hope long lost. Each high and low with this person will get worse and worse. My high and low with bipolar hasn't done too much damage to me yet... except for the hole I'm still in from psychosis, coming back out though. Do what you can for your own health and leave. Never talk to him again. The only way is no contact. I still think about the good times I had with her and they can remain with that.. But I now know that my future will be filled with more happiness and fulfilling life style then one based on lies and manipulation. Have faith in yourself and know that you are strong enough and there are better people. The longer you stay with him, the longer it will take you to get back into the right state of mind. Good luck.
