Sounds like my feelings dont count in this marriage?

My hubby of 3 yrs gets really mad at me when I say anything to about the way he treats his kids. His kids are 19, 18 and 16. The two oldest ones have quit coming around unless of course they need something or money. We still get the youngest one every weekend and the weekends revolve completely around him. My hubby takes him fishing, hunting, knife throwing, to shoot pool or whatever and I sit at home. My hubby and I both work full time and during the week we have no time together, maybe 2 hours per evening. My hubby pays child support faithfully and yet still buys the kids whatever they want, when ever they want it. We spent over $500 between Jan and May on the youngest one alone. When I said something to my hubby about this he got really mad and didnt' talk to me for 2 days, usually when the child is here with us. Even though I dont say anything to him in front of his kids. I am tried of us not having our time, him spending so much on these kids and him ignoring me unless his kids arent around. His youngest is very rude, disrespectful and says things under his breath to me. When I brought this to my hubbys attention he told me he wasnt going to say anything to his son about this because he sees how jealous I am of him? I know this makes no sense but thats the answer I got. I feel like I have no say so or that my feelings dont count for anything????
