Firstly you must be yourself. You are not there for anyone else when the time comes to part. He will hurt like hell, you might hurt, too, when you think back over the good times. But if it is time to end it, be gentle but firm. Don't let yourself be open to emotional blackmail. A true man will have to accept the inevitable, and take it on the chin. It's not going to be easy, it never, ever is!! You might both shed buckets of tears. That's all part of the process of breaking up. Don't be ashamed to cry, but don't be swayed if he cries too. And please don't be so down on men. There are some real good guys out there. My dad was one of them. He and my mum idolised each other. they were soulmates. OK, my mum doesn't want another guy, but it's not because he was a bad person. My sis and I had a wonderful childhood. I hope you will find a good guy, you are worth it. He will let you be yourself, will always be honest with you. Forget what his family did for you. You can't hang in there because of past events. I don't envy you and what must be done. All I can say is take good care!!

That attitude, as I'm sure you know, isn't healthy (the trust issue with guys). So it would actually be beneficial for you NOT to be in a relationship in my opinion so that you can work on it.
I would simply be honest with him. Go to a crowded place so he won't make a scene and break the news to him there. Tell him that you haven't felt like you wanted to be in a relationship for a long while and you only stayed out of fear... which is NOT healthy.
On top of that, he doesn't respect you. A guy who cared for you and/or was rational wouldn't get aggressive because you're trying to break up and call you names. He sounds toxic to me and I think being with him longer will give you a WORSE impression of your trust issues (and possibly men) then you already have.
Please get out. If you need me to talk to him or something, I will be glad to.
