What is a PC answer withou looking like a simp?

Obv. I'll be crusified if I say that I dont believe in marrige but on the other hand "havent met the right person" sounds pathetic.

Lately, I've been saying that I won't get married and it always ends up with more questions.

For context I live in über conservative place in EE andI'm approaching 30ies, its hard to explain to grannies at work that such questions are rude..
