My bf never gives me attention

My bf and I seem to be losing the spark, there’s been multiple problems in our relationship but the biggest one is his communication, he can go a day without talking to me. He works in the oilfield so he works a lot and when he’s done with work he goes straight to the casino to bet on football games and what not. He doesn’t really call me first ever, I’m always the one texting him or calling him, he of course answers but he doesn’t really give me attention anymore. Is this a rough patch or is this a deal breaker? By the way this has been going on for a while and I’ve told him multiple times about it but nothing ever seems to change.
