Lack of connection

My boyfriend and I have been together to a little over 3 and a half years. Lately I have been feeling really needy. We both work all week and it seems like we never have time to spend together. On the weekends when we could be spending time together he has his brother over and they play video games. I crave his touch and attention, not just sex but cuddling or just holding hands. He doesn't seem to notice or to care... what should I do?
