Is it normal for the husband to sleep in a separate room every night? - yes it can be. My DP mostly did, he snores terribly sometimes and I found it deeply irritating when I was up feeding baby and trying to get back to sleep.
Is it normal for me to settle the baby and sleep in this separate room and wake up to an empty house whilst he has gone to work? - normal for you to settle the baby, but not normal for him to go off to work without speaking to you. Unless he has to leave very early??
Is it normal for him to play golf every weekend? - that's not fair on you. When do you get the same amount of leisure time?
Is it normal for me to have to pay to get groceries delivered otherwise there would be no food or baby milk in the house? Well, I would normally have done the online food shop and arranged delivery and carried on doing that whilst I was on maternity leave. But if you mean that he knew that you hadn't got round to doing it and didn't care enough to sort it out, then that's not ok.
Is it normal when I had to take him to the hospital he drove in a separate car so he could get home? No, that's just selfish and inconsiderate. It also shows that he really doesn't view himself as a parent, sadly, in my opinion. He was just waiting until he could leave and leave you to it.
Is it normal he goes to bed when I am up tending to a feverish child? - it could be, if that's what had been agreed. But if you mean that you were massively sleep deprived and he didn't care about that at all, then no.
Is it normal he goes to the health club after work instead of coming home to help me? - no, that's not on either. When do you get the same amount of leisure time? It isn't "helping" either, it's doing his fair share of parenting, which he doesn't seem to think applies to him.
He doesn't seem to think that he is equally responsible for parenting and caring for your shared baby. I would be asking him why he thinks what he is doing is ok, because it's definitely not.
