I’m too autistic to understand this social personal question

Hi I’m Layla an high functioning autistic person here just want to ask a problem that I need help in.

I had experienced multiple times of the same situation with a problem that I can’t seem to solve on my is that i can’t seem to answer in a socially acceptable manner of how to react to this question: “do you have a girlfriend yet” or “why don’t you have a girlfriend yet”.

More context: I’m self aware to know that it is technically a social personal question that may be asking me (I’m the reciever) and the person who asked (the sender) whether maybe I’m taken or I’m not taken and etc

But the part that I don’t seem to executively function properly is that I already had feelings to my future partner (we talked a lot of our feelings and we both mutually had caught feelings for each other), the social problem is that my “relations” with him and I are that I’m a trans girl (closeted and plans to fully transition in the future once I completed my studies and get a job) and he’s a cis male, so clearly our relations with each other are not your typical conservative relationship.

The requirements at hand: So how can I find/create a solution where I can give a response that is : 1) socially acceptable without awkwardness

2) hides my gender identity from my parents (because I know my parents and I have two very different beliefs)

3) simultaneously not reveal a lot of information but technically answer the question in a way that doesn’t make me look like a disappointment to my parents and my relatives and my parents friends

If you have experienced this before and thought of a way to bypass this it would be helpful if you are comfortable sharing about it thanks
