My 2yo is bed sharing with me

Me and my son live with my parents. We have a roommate in the basement for right now so me and my son share a room. My son has been pretty good falling asleep in the crib up until now. A few weeks ago he got a cold and wanted to sleep with me at night. Since then he has just been wanting to sleep in my bed with me, if I try to put him in the crib he screams, gets really angry and asks for me until I give in and we lay down in my bed. My mom keeps asking if we should get him a toddler bed, at this point I’m thinking it’s pointless. We share a room anyway. What do you all think about 2 year olds bed sharing? Is there anything wrong with it? Looking for input from other moms with more experience than me. I’m thinking maybe I could just let him sleep in my bed for now and get rid of the crib to free up space. In the next year or so my parents are gonna kick our roommate out so I can move in the basement and my son can have his own room. At that point I’d transition him to his own bed…but I’m worried it will be too late and he’ll resist it. Any advice or thoughts from anyone on this?
