Unhappy in my marriage

Hey ladies I need some advice. My husband and I have been together for almost four years, married for almost two. Lately I've not been feeling very close to him. He's recently stopped drinking. He used to drink every single night after work like 5+ beers a night but now he drinks on the weekends. I'm thinking he may resent me cause I've requested he stopped drinking? Idk. Also for the last year we've had less sex. We have sex usually 3 times a month which is normally always initiated by me. He usually rejects me saying his stomach hurts. He's tired etc. I'm so tired of trying to help a grown man get himself together, I'm 23 and he's 27. He should be able to stop drinking for his OWN good, please his wife and help more around the house.. That's another thing he's ALWAYS leaving piles of clothes on the floor never cleaning up after himself in other ways. Ugh I'm sorry to be so negative I'm just so frustrated. I feel like a broken record because I've addressed these issues with him several times and he always says he will try harder but his actions don't match his words. Long story sorry guys!!! What do I do I need someone else's perspective on this ... I'm exhausted no kids yet with him we've been trying for a year but no luck probably cause we don't have enough sex.. 😒
