Am I being unreasonable?

I need a rant so I apologise now. My partner and I have been together 8 yrs, I have a son from a previous relationship and we have a son who is 3 months old. I'm on maternity and my partner works. I pretty much do everything which is fair enough as I am not at work but when he gets home he starts gaming, I swear it's like having a giant man child. I have mentioned on numerous occasions that I would like us to spend more time together once the kids are in bed but I'm lucky if I get that attention. I don't want to feel that I keep nagging him but I don't feel like we do enough together.

Is anyone else in this situation? I'm just getting fed up of being on my own in the evenings even though we're in the same house.
