my husband can't sleep with me in the same bed ????

i sleep with my 4yr and 2 yr but i want to start leaving at night into my husbands bed but now it's been for ever that we haven't slept in the same bed that's hard for me but harder for him.... the love passion everything is here except when actually sleeping in the same bed at night is it normal? Will we eventually get bk to the grove of sleeping together ?
