Could I have been raped?

Back in, I want to say 2018, I was at a gig at a bar one night when I was approached by a woman who iirc looked about 30 odd. I got talking to her for about half an hour or so before I was told where her house was and that I should pop over some time. I politely said maybe not thinking much of it. I carried on with my night, went home after the band finished, and never saw her again.
I never gave this event much thought until it sprang back to mind quite recently. Could this woman have tried something with me if I went to her place?
