He's Cheating

I always thought he loved me you know. The signs were present but i figured he loved me so its impossible. Just seen real physical proof and now im just im lost 39 weeks and 4 days pregnant ftm. I met his kids i slept on the streets with him because he had nowhere to go. I let it all go i kept moving forward and excusing him and what he would do. its not sweet its not cute its not ride or die of me....im just dumb. He belittled me calling me fat all the time everyday as soon as i wake up making fun of me he even put me last or most of the time didnt think of me at all. I broke my back for him for this I am so torn. I cant even cry right now because i just feel dumb but i keep tearing up( probably doesnt make sense) but what do i do now? I forgave him endlessly and now im broken. Maybe i wasnt good enough maybe i did something wrong. ive been so moody and we havent had sex. im just not good enough i guess. This whole relationship has been breaking me down. God im not good enough for anything why am i here? i cant even be a good partner. fuck.
