Young colleague showed interest?

I have a colleague who is 19 years younger. We do get along well together.

At one point, she asked where I lived. I told them which village I lived in, bordering a meadow.

Oh, good, she said. Then she asked about 'my situation'. Did I live alone or with children?

And she turned a little red. I said I live with my girlfriend and two children. Oh, she said.

It was in my head, a few weeks later I asked what she meant. I can't remember, she said.

Then I explained it again, I said that I had the idea that she liked me, but that I was surprised because she is 19 years younger. Then she said: I can imagine that I asked you.

What could this mean?
