Dating a gamer

My bf is a hard core gamer and I have very little experience gaming. He spends a lot of time gaming and sometimes it can be a little annoying when we’re apart cause he doesn’t respond to any texts. When I am with him I usually work on essays or whatever I’m doing at that time and just chill with him while he games. I guess my question is what can I do when we’re not together and I want to talk to him? I’d love any tips from gamers/people who date gamers, since this is an area I’m not very familiar with. All his guy friends game and they usually play together but I don’t have any close friends so it can get kinda lonely.
