<human>: Ever since we started dating, there's been red flags every where. I had many chances to leave him but never did because of that stupid "I will change, I promise". Although things have gotten much better and I'm not walking on egg shells, I don't feel respected, I don't feel loved, and I've never felt more alone in my life than now. 

He doesn't think the relationship is bad, but that's because I do everything for him and he doesn't have to give anything in return. I drive him to work, I cook, I clean, I pick him up from work: he comes home and sits in front of the tv playing games or melting into the couch until bedtime. There's never any consideration as to what I want to do. I can't go out and see friends because he always gets pissy if I don't invite him, even though he never wants to go.. 

It sucks, I want out but I don't want to hurt him and I don't want to tell him there's a chance we would get back together because I never want to get back together with him once we are done. I'm also kind of scared of how he will react. In the past he said if I wanted to leave, I could and he would understand... but he says a lot of things and reacts completely different when said scenario is reality.

Could you distill the essence of the text into 1-3 sentences?
