am I overreacting

my bf was a drug addict before was addicted to cocaine and everything he’s clean now and has been for a while and we also have a kid in the way. when he smokes he’s mean so I kinda started to step back a little and he realized and stopped smoking but it was getting in between us im 20 weeks pregnant. But we are moving into our own house next month so we’re packing everything but he insists to bring his bongs there and pipes it kinda upset me since he’s not doing it so why would he need them I just don’t understand why he won’t throw it away or leave them at the old house with his brother and it made me feel he was doing stuff again? Would u think he is? If he like made up a whole fight abt it
