boyfriend didn't text me all day

Usually my bf has work and works really late. But I'm so fed up with him not texting me all day. I know sometimes he just likes to be alone but if you're going to be on your phone why not bother to hit me up? We make time to see each other but a day without as much as a text is a little weird to me. (I don't suspect him of cheating either or wanting to end the relationship because we've talked about it) but does anyone who doesn't live with their SO go through this? 🙄
