Marriage roommates

My husband and I are pretty young me 22 and my husband 25 we will be married two years this year , we LIVE TOGETHER and PARENT TOGETHER, but it’s more like we’re roommates who have a good friendship . Our sex life is just about him and how he wants to be pleased , and YES I HAVE TOLD HIM that he needs to do more to me . The guy can barley last 5 mins smh ... anyway he hasn’t eaten me out or done anything in like two years probably. We almost got a divorce when our son was born at 26 weeks my husband couldn’t understand how I didn’t want to be at home and only spent time with our dying sick son . He only went to the hospital 4 times and held our son twice during our 3 month stay . But I get it some men can’t handle that shit . So I let go . I don’t know what to do . I’m a stay at home mom so it’s not like I have anywhere to go or any money to do so . I’m at a loss . I really have just givin up on trying to fix our marriage . My husband also is lazy as hell and rarely helps clean the house . He always waits until last mins and if I nag at him he refuses to do anything . I just know there is someone who actually deserves me out there . I just have no idea how to leave . Picture of us on our wedding day .
