I dont know if i should give up and leave?

Should i tell him i will support you from a far but i cant continue?

So for context me and my bf know eachother for about 8 months weve been together for 3 months. He wanted to be with me ages before we got together. When we got together everything was fine. Hes responsible,respectful and consistent .

I traveled for a month to meet a fam member. We barely text and we rely on calls . He gets too busy and sometimes isn’t ready for calls, and im understanding.

Recently he met a famous girl he was claiming he met her from the group chat ( he has a big groupchat of friends that keeps adding peope) one day he told me shes asked him and others if they would get in a youtube video. He said are you okay with me being on social media and he was saying my opinion is important and that if i dont want him to he would not do it. Obviously i would not stop someone from something they want to do .. its his life.

2 days ago hes been acting distant and weird he just wanted space. He kept ignoring the fact he acted like this until i was like hey whats wrong. He was like its smth in my head i feel im wasting time. And he was acting like he was wearing a mask theres literally no connection. Then he said he will start social media and he literally said smth way diff from what he said at the start. Now its like they both will start youtube and he said they will meet up this week in a restaurant or caffe to plan everything just them two. He said he told her he will also help her in the future = its a long term thing. He said if u want she can talk to you and she asked if ur okay with it . I said no dont need to talk.

Now im hesitant do i wanna continue? Its his life i will never tell him dont do it. Its his opportunity. I want him to succeed, but i dont think i wanna continue he will meet up with her alone from now on and make vids and hes been calling her … and i have strict parents so i cant just go with them
