Negative nude experience

So my boyfriend and I have been inseparable for a year now like literally work sleep eat go out together up until this Monday when he swift opposite shifts as me we work twelve hours and live a hour from work so we see each other for less than five minutes a day at work as I’m clocking out and he’s clocking in so Today I really missed him and sent him a sexy picture he literally just ignores the photo in all and responds to a previous text and never even commented on the photo I don’t know I feel like super emotional and like he doesn’t want me anymore I guess
