I couldn't love you but here, have some money

It sounds like a really horrible experience, but I don't think his attachment style is the only problem here. What do you know about yours? You might want to work hard to get a handle on that, otherwise you're likely bound for a repeat with someone else. He doesn't have any magical hold over you, your choices were deeply dysfunctional and all your own. I am pointing this out because you can't do anything about his issues, but you can do something about your own, so that you don't engage in damaging situations like this. I have learned over time that I am responsible for the quality of my relarionships, full stop. If there is something toxic going on I'm a participant, there's a path I walk to get to where I am, where ever that is.
