Manners

My husband has no manners literally doesn’t give a shit what he’s doing or how he Is looking, I don’t usually ever care about stuff like this but it’s getting to the point it’s actually a bit of a put off😫 he sounds like an actual animal when he eats chewing with his mouth open to the point now I can’t sit and eat with him because he says he’s done it all his life he can’t change now which I get but I don’t understand how hard it is to just keep your mouth closed! Lies with everything hanging out takes up the full sofa you need to ask him to budge up so you can get a seat but if we didn’t ask he wouldn’t offer, sex isn’t great also due to the weight he’s put on which isn’t the main problem I don’t mind that I want to help and encourage him to get into a better place but he just doesn’t give a fuck claims he does but if you suggest a walk or anything he moans about how he just wants to relax after work! He also burped in-my face during sex a few times! When having sex it’s just one motion and it’s doing nothing for me but can tell he just cares about what he’s getting not really fussed about me! Anytime I try have any conversations with him or tell him a story just to try have some 1:1 time he is so negative and moany it’s just draining now, he’s doesn’t care about saving money, I saved money in a tin for our kids and he got drunk and started a fight with me cause he wanted to take it to go out! I really don’t know what to do if I try talk to him he never sees what he’s done wrong and tries to spin stuff on me
