<human>: The relationship has always been rocky.  My love for her is the only thing that's kept us together.  We should have broken up, a lot.  

Over a year ago she started a business that I unwillingly became a part of.  

Then she pressured me into moving in.  

I haven't wanted to be with her for quite some time.  She has a lot of unresolved issues combined with the fact she's very immature.  And she's very high maintenance.  I care about her. But our relationship is killing me.  

I haven't had the strength to move out/break up for much of our relationship.  She holds some kinda power over me.  Recently, I got fed up.  I tried leaving her twice but she threatened to kill herself.  I tried leaving her again but she somehow convinced me that I was crazy and everyone knew it.  She made me feel isolated, betrayed.  I tried to leave her again but she told me that I should stop blaming my unhappiness on the relationship and start finding help.  

I don't want to be with her in this way.  I don't want to be with anyone in this way.  The longer I am with her the more I hate myself, the more miserable I am.  I feel like I'm being suffocated.  I feel like there is no way out.  Please help.
