I've been chatting with this girl for about two months now. Often, when I try to video call her, she doesn't answer and mentioned that I should request permission before calling on video. Have any of you, both guys and ladies, encountered a similar situation? I'm seeking input from everyone.

Yes, permission should be taken before you initiated a video call.

Don't just intrude on people's privacy.

She's either living with roommates, or having a very creepy looking room. Don't expect her to answer the call. Secondly, our people are not used to that. Thirdly, you could break up with her and your call could drive away potential husband for her. So, try and respect her privacy and control your urges, otherwise it will land you into problems one day.

He's not even her boyfriend yet.
Apologize to her for intruding her privacy
