Do you and husband/spouse go to bed at the same time

So weve been together 10 years and now husband never comes to bed with me at night. Its been around 2 years of the same. Granted the first year i was pregnant amd would need a early night but baby girl is over a year old now and obviously everynight when im going to go to bed i ask him if hes coming. His answer is no not yet. Then he will proceed to stay up for a few hours more meaning i will always go to bed in a empty bed alone. It makes me sad and iv told him but he says im being controlling telling him when to go bed and that hes not sleepy. I dont mind if he needs his time some nights but just not every damn night. In the last two years weve probably gone to bed together maybe 4 times. Just want to see how normal this is in peoples relationships?
