Ask QC: An ex From Twenty Years ago Reached out to me, and now he is a she

Nearly 20 years ago I was dating a guy, it didn’t work. Our split wasn’t a horror show but we did not stay friends and I’ve not spoken to him since and haven’t thought of him really at all. Recently, he reached out to reconnect, but he is now she.

I’m confused as to what she wants from me. We are not friends. I’m unsure if I want to answer at all, or just let the past stay past. Maybe she has unfinished business with me? But I’m just not interested if that’s the case. This feels like a shitload of drama waiting to dump or I’m overthinking it?
