Why my crush hasn’t put me in his private story while my friends are in his story?

It been year, I haven’t got added to his private story. My friends knows I like him and they would tell me what he been posting that I don’t see. I don’t say anything to him but he tells me his personal stuff at home. We sometimes text but It just work, school, schedule and his talks. He tells me his plans in the future but he hasn’t told his friends because they snitched. Basically I know what going on his life and his business. We both work in the same company and I don’t see him that much since he works somewhere like department. We sometimes eat in our lunch for work then just go back to work. He is very bipolar person cuz sometimes he can be mean or nice or petty and I just handle it. I just understand why I’m not in his private story. Like what is going on? I hate when I’m near his friends at work and my friends talking about his story while I’m here like wtf I’m suppose to do by acting stupid or walk away like sheeet what do I do?
