Need help weaning and sleeping in own bed

HELP! I know this is my fault for letting it happen. My boy is 15 months old and we’ve been bed sharing since he was 2 months old. It’s what worked for us. I’m also still breastfeeding and want to wean. I don’t even know where to start to get him to sleep in his crib and also weaning him from the boob. He really only nurses 2 times per day and sometimes at night since we bedshare. I have been trying to not let him nurse yesterday and today a couple of times and he threw a huge fit. Literally a temper tantrum for over an hour until he passed out. I felt horrible, but I’m not sure what else to do 🤷🏻‍♀️ I’m just ready for my bed with my husband only and body back.
