My birthday

Today is my birthday, and my boyfriend didn't say anything even we chatted for hours. Maybe he forget, or he doesn't care anymore.
To be honest, I feel doubt with this long distance relationship. Maybe not doubt, let say I'm so afraid to lose him. He is the reason why I still alive when I felt there's no hope.
He is my future, he is my goal. I do everything to make my self better to proud him.
And lately I feel doubt with him, or my self, because I can't make him proud. I'm still nothing to proud him.
He never say anything, and he is still normal like we used to do. I don't know what I'm worried about or I just overthinking.
