Boyfriend probable Sociopath

I have been with a man for the last year whom my family counselor advises is a probable sociopath. I am having trouble completely disengaging myself from him even though I moved him out of my house while he was away about a month ago, ( I could not take the verbal abuse, my children were scared for me). He threatens me with suicide and then breaks my heart with his vulnerability. He has isolated himself from his "friends" and family with the exception of his aging father whom he says, "does not want or need the burden. " He has no desire to work nor has he for around five years. He had been trying to get me to hire him and pay him to take care of my home while living entirely off of me. Now he is trying to get me to rent a room to him which he will pay for by working at the house while I remain his girlfriend, this while not trying or even addressing my concerns, wants, or desires in this relationship. Everything is supposed to be mutually beneficial , but truly it only benefits him. He is currently two hours away with all his belongings in his car, sleeping on his dad's couch in a travel trailer. When he comes to visit it is a fight to get him to leave, long hours of verbal abuse, suicidal threats and superficial self abuse. I feel very guilty for the way I handled things and the living condition he is currently in. My mind keeps telling me it is not possible for him to love me the way he says or thinks he does, that he is using me, but my heart wants me to be wrong. He does fit the PD with few exceptions; I have not caught him lying, cheating, or stealing, and he can be very self depreciating. He abuses alcohol and pot excessively, it seems almost medicinal. Guns, knives and security are an obsession. He claims to have seen awful things such as ghosts, demons, UFO's, and admits to being depressed. His mother is bipolar and his dad is a loner who stock piles a storage unit with large amounts of ammo, firearms and survival gear for the "end of days."

I have been legally separated from my husband for one-and-a-half years. I was bored in my marriage and probably on the verge of sabotaging it but my husband beat me to the punch, so I guess you could say my boyfriend found me during a vulnerable period of time. This relationship has made things harder for me with my ex. I am very attractive and am financially well off but in my early 40's, postmenopausal and apparently going through some kind of midlife crises. My boyfriend is quite a bit younger than me and it has only deepened my insecurities. I guess I am writing this because I hope to get support to help me finally end it, and or maybe get more facts about the PD to help with the nagging question in my head...
WHAT IF I HAVE HIM ALL WRONG?

The label isn't important, and even if he was a sociopath, this wouldn't give him the excuse to abuse you in this way. What matters more is how YOU are feeling, how this abuse has made YOU feel, and where you go from here.

Therapy can help you to work upon your self esteem issues that have been caused by past abuse, and which keep you in a situation where you are being abused. Working on yourself, and finding a way to escape this cycle of abuse is what's important.
