I totally agree that we make our own happiness and it is the choices that we make which determine that happiness. But to be fair, I have known people who have been able to just walk away from a relationship like this, and others who have a hard time out of fear. If you can walk away, great, I think that would be the best thing to do, but if you are scared, then sometimes it is just not that easy. You can make it happen though. You have to decide, are these demanding and dominating features things that you are willing to deal with? First thing is, if you are willing to deal with it, then you are going to do just that. Stay and deal with it. If you are not willing to deal with it, then you will need to takes steps in order to get up your confidence to leave. That may be by support of friends, family, church or whatever resources you can find to make a plan to make yourself happy. I know that people can change and become more demanding as time goes on, but me personally, if I had any thoughts about a person being that way, I would leave at the first sign of that. I dated this guy once as a young adult. He told me that if I ever talked to this specific person again that I would be in trouble, kind of threatened me. That was the last time I ever went out with him. I just knew that if he was trying to dominate me like that, that the future would be trouble. So try to be smart in the decisions that you make.
