Should I move in with him???

My daughter and I have been living together at BAE’s place for almost a month now and it’s been great. I recently started having cold symptoms and decided to go back to my moms with my daughter to self quarantine until I’m better...he has sickle cell and I don’t want him to get sick with whatever I have going on. He really wants us to stay but I’m not going to. We’ve been Messing around on and off for a couple years and now it’s been exclusive (going on two months). I feel like moving in is great because I’m still living at my moms (paying rent and on the lease) but his place is smaller than I’m comfortable with. Should I wait to move in and we can look for our own apartment? Or is it too soon to move in?
