LDR advice

My bf moved to another state for work for 6 months. It's been a month and at first we were completely fine just how we thought we can go through it but this week and some of the week before his hours are up to 16 hrs a day so sometimes talking/texting is very little. On Thursday I kind of gave him a hard time about (I been somewhat compromising about it) and he went off that I think it's easy for him and it's not at all he's just so busy so on.
