My boyfriend doesn’t text me like we used to

My boyfriend works all the time. He doesn’t text me like we used to before. We used to text everyday and now he is just busy at work.
We are dating long distance so texting is the only way to be together.

I am kind of mad at him because he has 24 hours in a day and he can’t even make a hour to talk to me. I don’t mind him working.
I want him to work and also talk to me.

I haven’t said anything to him. I let him work without letting him know how I feel. Even though I am letting him work in the time when we used to text, I feel so sad and heartbroken.

I also decided to work on my business since he doesn’t want to talk to me but I still feel so sad. I want to talk to him and I keep constantly checking my phone to see if he has sent me a text.

I am okay with feeling sad and heartbroken because it’s my manual on him that he should want to text me. How to be okay when I miss him so much and want to talk to him and not make it mean anything when he doesn’t want to do it.

I want to talk to him so bad but also want to honor his decision and let him work. How to spend time alone with myself having fun?
