Wow! Sad to say I have heard this type of story many times and kudo's for not giving up as when you do find the right person, it is so much better.
As @Turkey1 as made some good suggestions and would like to add to that. I would be careful of the people on FetLife as many are not as they pretend to be. I usually find myself giving this advice to woman who are dealing with men but I think the following is applicable regardless. Meet the person in a public place for coffee/tea, and talk to them as equals. Observe what they say and how they say it, how do they treat others, like the wait staff, order taker, etc. Do they treat them with courtesy, politeness, good manners or are they demanding, rude, dismissive. Think how this person will treat you if they treat someone else poorly. Over 20 years ago someone in the scene said to me, if someone behaves a bit like an ass in the vanilla world, it is going to be magnified in the BDSM realm. So a little ass is going to be a big ass and that is not going to play well if you become the victim. I have said on this site somewhere, e.g., the good Doms and Masters seem like ordinary people, no air about them, no constantly proving who they are. They are polite, respectful people, easy to get along with, they don't expect to be addressed with a title, or be called sir. If you have good instincts, listen to those instincts as there is something going on despite the fact you can't put your finger on it.
