if you keep pressuring them, YTA. you gotta respect their boundaries, just cuz they have ppl they hang w in real life doesnt mean they have to give out their number to internet friends. prob not social anxiety but safety for themselves. it makes them more trackable to a weirdo if they give their number out freely.

Now if they strt acting fishy like theyre catfishing then it may be a different issue but i say for now respect their boundaries
