HIS HYGIENE IS RUINING US. 😷

My boyfriend and I have been together for almost 8 months. I love him so much and I believe that he’s my soulmate. BUT his hygiene is ruining our relationship. His room is a DISASTER. He has like 6 trash bags full of trash stuffed in the corner that’s been there since we started dating! He kills spiders and leaves them splattered on the walls. There’s been a dead fly on his fan for months. He pees in cups if he doesn’t feel like getting up and leaves them sitting around. He doesn’t take care of his appearance either. He has an overgrown beard and I’ve been bugging him to cut his hair for months. He wears the same clothes even if they’re dirty, wrinkly, or smell to work. He doesn’t wear deodorant and often smells like BO. He has visible plaque on his teeth and it grosses me out to the point I’ve stopped kissing him. I’m the complete opposite of him. I’m neat and take care of my appearance. I will never leave my house if my room isn’t clean or if I don’t look put together. I’m going crazy because our relationship is perfect otherwise! I brought this up gently last night and it exploded into a HUGE argument. He’s acting like an immature baby and I just don’t even know what to do anymore. I’m just so frustrated! By the way he’s 24 and I’m 18. Please leave some advice for me!
