Feelings can cloud a person's perspective. You have to be very objective here in your assessment of this man as a father figure and partner. He hasn't been a good partner and he has a very sketchy past. He will disappoint you and will hurt you as a partner and he will disappoint you as a father figure. If you had a girlfriend, daughter or sister who had a partner just like yours, what would your advice be?

Your title in this thread states he is a sociopath.... and you mention this in your post. So why go down this road with someone you believe to be sociopathic? Sure, you can have feelings, but be objective. He is no good, and the sooner you get away from this man the better.

You also have to ask yourself what your standards are in men. Are your standards so low that this is what you are willing to accept in a man and partner? You have two masters degrees and are clearly accomplished. This man is a jailbird bum with no work history - you had to push him to get a job even and he's resorted to drugs. And he lies to you. Why put yourself through this?
