We met in an app.
She made it clear that she wants the D.

We meet for a first date, drive in a car somewhere, things heat up.
She tells me she's a virgin and wanted me as her first.

We have fun for an hour then I get her back.
I write her Good night, Next morning (very early) she texted me with a smile.
Then she disappeared - didn't reply to my another message.

I send her a message again after 1.5 days about getting something to eat.

She immediately replies "Hi. Who is it? I lost my contacts"

I reply to her by saying my name and that we met.

A day passed and she didn't reply, so I sent her a "farewell message" (the "wish you the best" kind of thing).

Then after a day she replies that:
She's sorry that she didn't answer earlier. She had a good time and had a connection, but she's not looking for it now - it's difficult for her this way.

I don't understand what happened here.
I made sure she would enjoy and it seems that she did.
But still doesn't want to meet?
We also have good chemistry.

Would appreciate the wisdom of the folks here.
