Help!!!!

No idea where to start on getting my son to sleep in the crib. He’s been sleeping with me since he was 1 month old. He used to sleep swaddled in his bassinet then it just sort of happened. We have a king bed so I didn’t mind it , but he’s super clingy now and can’t be swaddled and no matter how low the A.C is I sweat alllllll night. And I’m also super uncomfortable since he wants to be on me. How do I get him to sleep in the crib. He would only sleep an hour or two swaddled in the crib. But he can’t be swaddled anymore. I tried the weighted sleep sack but that doesn’t work at all. I put him down and he starts crying awake or asleep. Please help :( what did you guys do or are doing to get your LO to sleep in their crib!
