So about one month ago I met this girl. She acted very interested, great connection, and after a couple of dates she came to my house and we had sex. I thought everything was going well.

Then, we kept texting and seeing each other regularly, but didn't have another occasion to have sex until yesterday.

We had lunch together, having a great time as usual, then she invited me to her house, and we got on her bed and started cuddling. But then, I tried to initiate sexual activity a couple of times and she declined. I asked what was going on and she said she just wanted to rest. So I stopped, and after a while she said to go out again.

We went for a coffee, then I said "so, better I go I guess". She insisted to stay with me for some more time, and she acted very kind, kissing and hugging and etc, while we walked until we get close to my house. Then I asked her to come in, and she said no.

What the fuck is happening?

PS: no period.

TLDR: great connection with a girl, had sex once, now she is avoiding sex but still wants to see me.
