Sleeping in 2br

Do you think there is problem if you're married and you're sleeping in 2 different rooms???

The reason I ask is because lately me and my husband have been distant. It just seem like we have grown apart and we can't talk to one another. It's like we are just co existing. We have 2 kids and it's just feel like we grown apart like we let the love just slip away because we came too comfortable. I asked him why do he sleep in the other room and he says because the kids get in the bed and it just feel like we grown apart. Our love life has even been gone. We at the point where we are like:

Can we recover from this? How did we let each other get too comfortable?

He won't even get in the same bed with me.
