PP depression or I need to move on

Hi yall I need some light and also vent so is gonna be a long post, please read it and give your point of view don’t matter what I’m not sensitive. So me and my bf been together for 5 years now, we met online and after meeting up it was an instant connection kinda, I was single(but not alone) for a long time and didn’t care for a commitment but he kinda push it and we ended up together, everything was fine not 100% but he’s a good man and I have a bad temper that always been an issue some how but he’s learned how to deal with it. Anyway during covid on 2020 we were only 1 year in and both were not working for months so we spend a LOT of time together and I felt like he was not letting me breath, he gained a lot of weight like 80 pounds in that year alone keeping in mind he was already like 250 before but he’s tall, it wasn’t an issue until it started being one like I stopped feeling attracted to him, slacking on sex and overall just not ideal, he started working over nights and everything just got worse as he works sitting down he’s now almost 350 pounds and we have the losing weight conversation so many times he always says he’s gonna lose weight workout bla bla never happens. We have a 2 yo and when I was pregnant we moved together and it was hard, he is the type of person who don’t clean up after himself or clean up in general unless I say something or he knows I’m mad about it which is something that makes me mad, we have 4 months twins as well and I stopped working since 7 months pregnant, we had some struggles because he don’t make enough even tho he works overtime to be comfortable but also makes a lot of bad choices with the money but we manage at the end of the day I know is a lot. But since he works overnights he sleep during the day while I’m by myself with the kids that you can imagine is a lot, even on his days off I feel like he don’t do enough he’s always tired and OVERWEIGHT plus I’m mostly always tired and overstimulated in a bad mood, I don’t even want to see him or speak to him when I’m mad I just ignore him and he knows not to bother me, we don’t have sex because I’m always tired or he’s not home and honestly I’m just not attracted to him I feel like I’m going something against my will I try to avoid it, I’m not in the position to split since I’m not working and have 3 little kids but I think a lot about if this is the life I want. Plus he became so Boring we used to go out a lot but I’m home 24/7 and is killing me. Like I said he’s not a bad man he don’t go out and I never felt disrespected or he never done nothing shady but I just feel like he aggravates me more than anything everything he does bother me some days. Sorry I try to not include everything to not make it long but I have a lot in my chest. Thanks 🥲
