Falling out of love...

I know I made a commitment before God and everyone for better or for worse... but I can't do it anymore, he treats me horrible, I do EVERYTHING for him. He's extremely lazy only goes to work and does nothing besides sleep and video games other than that. The treating me horrible part started recently. He always chooses his ps4 over me. If I run out of an ingredient while cooking he won't leave his game to get it he makes me get it. I can't respect him. I think I'm starting to fall out of love with him and that scares me. I don't want to be just roomates. I don't think I even want to have his child ever. I'm so tired of always crying and getting treated like crap. He blames me for absolutely everything and I can't tell anyone I know anything. I'm just so tired and heartbroken. He's not who I thought he was.
