I dont think I have a husband anymore...

I have 2yr and 1yr babies. Quit my career because hubby wants to work. He work 6pm-2am but he always have to overtime till 5am... He wakes up about 3pm to get ready for work again... my point is I feel like I dont have a husband anymore. I ask him a few times alreay to spend atleast 1 day with his kids but he always say he'll try. I have to beg for his time all the time. If I get angry he would still blame me... im being selfish and blah blah blah.... Am I being selfish for wanting to spend more time with him with kids?
