It sounds like you need to make a lot of changes and perhaps face a lot of truths about yourself.

I firmly believe if a person mistreats you, it's because you mistreat you.

Or to put it another way. You ARE what YOU think.

So you have to ask yourself, is there some kind of issue you have with yourself, some kind of negative core belief which you have which is attracting this sort of person into your life. You must have some kind of idea why this is happening to you.

You obviously believe the answer lies in a forum. How can a person on a forum tell you about yourself? They can't.

And if you don't know yourself, how can you even begin to know someone else.

You can love without the need to be loved but first you have to love yourself.

And once you discover this, you will attract the same self loving person into your life.
