Overly attached baby

My 10 month old has developed a really strong attachment to me (not saying it’s a bad thing at all!) however it does prevent me from doing things like cleaning, showering, cooking (for me & my fiancé) etc. My fiancé has said several times that “I don’t make” time to be intimate with him. Cause the baby has my attention 24/7. I can’t help that he needs me, but I do wanna try to wean him a little bit if I can. I can’t hardly put him down without him screaming. I’ve tried a little bit of everything. I finally gave in today & broke out our carrier & that is where he has been (strapped to my chest) ever since. He’s the most content with being held by me & I couldn’t take the constant crying so I had to do something. He also doesn’t sleep well. He has me up until 1-3am & right back up around 4-9am. I like for him to get at least one nap In a day, but sometimes he fights me so bad he doesn’t even take one. Other days he takes multiple naps. I’ve noticed with or without naps he still puts up a hell of a fight to go down for the night. I’m a first time mom & I’m just at a loss...how do I wean him from me (a little bit of breathing room is all I need!) & to sleep better throughout the night? I’ve tried the CIO method last night. It worked okay, it took him 45 to fall asleep. I had about 4 mental breakdowns within that time 🤦🏻‍♀️ I’m thinking about maybe doing it again tonight? I haven’t seen major improvements though.
