Anyone else struggle with a boyfriend who likes to play video games and smoke more than life itself??

Ra
Oh my God.
I swear it's the breaking point for me and my dude. Video games are his life, and smoking weed is life for him. He has s job, but the first thing he does after he comes home is smoke, then hop on his gaming system. He'll occasionally come to check to see if I'm still alive!!
I told him about it, and he said it's something he likes to do, and that I just need a hobby.  WTF?? Like working full-time and going to school full-time isn't enough? Whenever I ask him to come laydown with me or if we could go somewhere fun, he replies, "I don't want to lay down!" Or "let me finish playing the game first." I never really bother him when he has his game, but come on! He's 28. While he's smoking, he'll watch YouTube videos until he's ready to play his game. 
Then to make it worse he'll turn around and ask me, "so, what's for dinner?"
