Because you don't have abandonment issues, your parents have been "there" for you. You have been willing to sit and talk, but he pushes you away and avoids it. You are healthy in that you are willing to see a therapist, he won't do that and says it's for weak people. It isn't for "weak" people, it's for people who have challenges to get help in understanding and dealing with them.

Yes, we do have a variety of people out there in the world. You are young and come from a close and caring family so there "are" going to be individuals out there that just may take you by surprise. It's important to learn how to recognize the "red flags" people give off that mean they may have problems that are best for you to stay away from. When you met this guy you were very young and maybe he felt he had "more" control because he is older. Well, now you are in a position where you "can" be more independent, he is considering that a threat. I personally think that is stemming from his mother just up and leaving and dumping him at his father's. Children "never' really get over that and show that by their "need for control" and battling their own "inner fears". He saw his father own a home, working hard and his wife just up and leaving, so seeing something like that happen can really settle deep down and "imprint" in a child's mind that can be a little voice of believing that is what will happen to him too. Tricking you into signing your rights away from the house was him already preparing for that. He probably saw that his father had to give up things when his mother divorced him, his father probably made comments about it in front of him. And no one was there to cook and clean and fold his socks when his mother up and left either.

You could spend your entire life having to take "the blame" somehow for that deep challenge in him. Well, that is not a healthy life long relationship.

It "is" sad that this challenge is created in people, as often it lasts a lifetime.
