<human>: I should not have married you. But we got pregnant and I wanted to do what I thought was the right thing. It was not the right thing. It may make me an asshole but I didn't want to be a step dad and you knew that but you kept persuading me into it. I haven't accepted him as my own. That makes me a terrible person and i'm ok with that but at least I know my truth. I am not a stepdad. Im a great father to my own only. Its the sad fact of my life. I didnt want to be with someone with so many crippling issues and drama. And yes, it may make me an even bigger asshole but i didn't want to be with someone who was overweight. I fell in love with who you are as a person. Your obesity disgusts me. Your anger scares me. Your failed relationships, your shitty past, your codependence with your mother, your laziness, your hypocrisy, all repulse me. You have lost yourself. You are not who I met. You are not worth fighting for anymore. My only regret is not ending it before we got pregnant, now its more complicated but it still is inevitable. I am faced with the choice between my own happiness (moving out) and their happiness (staying together). But I can't do it anymore. I cant be angry everyday. I can't wake up and realize im stuck in a nightmare day after day, year after year. I'm losing myself just like you. Im unraveling. I can't get excited about anything because I know it will have to include you two. You think im a quiet person. You think I have no passion, no life goals, no romance, I do they just dont include you so I keep to myself and gently coast along day by day and hope for a time when I either get the guts to leave, everything changes somehow, or i fucking die miserable and more alone than when I was actually alone.

Give me the gist of the text in a nutshell
<bot>: I wanted to break up when we were dating but i couldn't, we got pregnant, married, was an asshole stepdad now 5 years later its ending because I can't handle living with her and her son.
