Is there someone out there who can love me and have some common decency and respect?

People will push us to our limits until we set some.
She can only disrespect you to the amount that you accept.
Stop giving to her and see how long she sticks around.
If you love this person...go to a professional therapist...
Start respecting yourself and life will mirror back to you that respect through your relationships.
You have low self esteem...so even if she leaves you will still attract your own issues being played out on the big screen of life....we are here to heal this so we can truly love and be loved in return.....seek a therapist who can help you get to the core of your feelings and you will find self love and real love in life.
It is hard and takes courage but you so worth it !
It is the true spiritual journey and what you really came here for...you can't escape it.....so jump in !

You are going to the one who first shows common decency and respect if you ever hope to wind up with someone like that.

have you told her how you feel?
If you feel so badly disrespected you need to find someone who deserves you, yes there is someone like that out there that you will find, just play the game while being aware until you are sure

Yes

Of corse there is!

I hope so, and that you find them.
Maybe it's time to call it a day with this current woman?
It doesn't sound as if she cares about you at all, so time to move on?
