I need to stop help

It's hard to say without knowing you. Perhaps you have shitty taste in men. Perhaps they noticed a flaw that you haven't been aware of. If the latter is true, then I'd suggest a little introspection and focus on improving as a person. You could either sharpen your strengths, or shore up your weaknesses.

Take this test. It will give you a 4 letter result. Type in google "XXXX relationships" and click the first link you see. If it describes you well, it will have also described your strengths and weaknesses even within a relationship context and should give you the tools you need to know how you can improve as a person. The test isn't perfect, but it has pretty good "test re-take validity."

If the issue is your taste in men... Well making sure you learn from your experiences is my best advice.

I hope this helps.

"After a few days or weeks they block me or tell me they hate me. Most of them say I'm annoying because I actually care."

Is the, "... because I actually care", bit your words or theirs?

If you nag other people so much that they say you're annoying, and actually block you then it's not about caring, but rather it's more about you smothering them and chasing them away.

stop dating men for a year. you have no direction , you are not with a man you mount them for a horse ride to nowhere. then you wonder why they buck you off your their backs .

Lighten up. You are not a fighter you are a lover, throw your head back Smile, arch your back, expand your chest
A man will do whatever dad's little girl wants but will walk out on a domineering
Complaining mother type.
Put your head on his shoulder and say Daddy will you do it for me??
He would be so hot for you He will put you on a pedestal and lay gifts at your feet

Maybe try putting the guys needs first occassionaly. Stop being a nag too, there is nothing worse than that. Some mommas boys like being led around, but most don't.
