Only you can make yourself feel inferior

I am in a funk today...
I am in that place where my heart hurts... I cried all weekend, I feel drained, exhausted... empty.
I was a stupid, stupid girl...
I walked back into my relationship that I walked away from eight months ago.  He came to me with promises of change, even made those changes... and they lasted all of two weeks, and now its been four months of being together and we are back to where we were.
Only this weekend... I think I realized how little he truly does care.  I realized that I am only there for him, his needs, and making him feel better about himself.
When I comfronted him about this, and him not putting any effort into me.. he blew up at me and turned it around to what all I dont do for him and how I never make him feel loved.  It really hurt, because this time, I did everything he said I didnt do and more... I went above and beyond.  I realized he will never love me for me, and I feel hurt, crushed... and yes, inferior.
The thing was... I was scared he was going to leave me.  I dont want to be that girl... who stays with a man just to have someone there... who went back into a relationship I knew would never work, with hope... only to find out it was worse than I thought....he never cared.  He doesnt care... and does not plan on doing anything to show he does.
I feel done... its just a matter now of getting that courage to get gone, and stay gone... I just feel so hurt and alone right now...
