Feeling alone..

I'm a sahm of 3 kids. My husband works 5 days a week and has a hot rod as a hobby. When he's not at work, he's either working on his hot rod or helping his buddies on theirs. I know he needs his "me" time but I'm here all day with kids. I just want more us time. I have so much I want to talk over with him when he gets home but he usually eats then falls off to sleep on the couch. The weekend is usually when we have time to spend together but he's usually doing the things he wants, like working on his hot rod, helping his buddies with their hot rod or playing video games. My husband loves me and our kids but he keeps his self so busy. Anyone else go through this and sometimes feel alone?
