Phone addict much??

Three times now we have been in the middle of sex and he has either checked his phone because he was in the middle of a trade of stocks, or he answered his phone when someone was calling him. He swears he wasn’t thinking and was just a reaction and realized he did wrong as soon as he did but it’s been 3 times now. It’s hard to fully express how insulting that is, and I promise, the sex isn’t bad at all, it’s definitely by far the best we’ve either had, but I guess his phone take priority. I don’t know what to do.
