Bedtime help!

Ok so my 6 month old has been cosleeping with me since 4 months and I need to try to get him to sleep in his crib in his room and need help. First, we just moved (2 weeks ago) to a new bigger apartment, from a 1br to a 2br so he could have a nursery. Second, he used to sleep in his crib next to our bed in our 1br until 4 months and then he started fussing through the night and i needed sleep so it just happened. Third, my mom, my ped., my MIL and my SO have all been hounding me since i started cosleeping and now hounding me to get him to sleep in his crib. My SO cant even sleep in the same bed because hes a light sleeper and the baby kicks and makes noises. But also my SO sleeps on the couch when i snore anyway, so at first, i wrote off his nagging but he is right and he works hard and hes paying for this big apartment so our son could have his own big beautiful room. Anyway, i know the baby needs to sleep in his crib and i have always preferred that, but i got into this habit and i am having trouble getting out of it. I feel like i have tried everything, including letting him cry it out and he just cries and screams. Then my SO gets annoyed and I dont understand why he doesnt try it and see how freaking hard it is to get this baby to sleep in his crib. So i just keep giving up and bringing the baby back to bed with me. Ugh! I really need suggestions because I am so sick of the nagging but no helping!
