Teacher asked me Are you single

So today was my external viva and the external was a pretty teacher. When my roll no. Came then out of nowhere she asked me "Single ho" she was really pretty and sweet her age might be around 25-26 and when she said that , for a second my brain got freezed I was like whaaaatt. And then she started asking about my hair btw I am a curly hair guy, like how did you grow so long hair I mean we were two guys there but still she was asking me about all this I don't know why. I was not able to answer about that Single wala question. I am really confused like what she wanted to ask exactly and I waited for her to ask about that but she was busy in taking viva of other students so I guess I fucked up and not able to see her again. Please do let me know what she really meant or am I overthinking too much about this.
