I’ve had something similar twice.
The first I met about 2 years ago, and I’m sure I’ve mentioned about on here before. Went to hers, got along really well, both in relation to sex, and just basic chit chat etc after. I left that punt, and we continued to text each other daily. On the 2nd punt, I offered her the payment after the deed was done, and she refused to take it. The 3rd punt the same. I’ve been seeing her once a month or so ever since, no cash exchanging hands at all. Infact, I’d say she’s the one paying me, as every time I go to her place she gives me a present of some kind. Have even done over nights with her.
The second is which I’m currently going through. Normally, the prossie always asks for the money first in my experience. Not this time. We had sex, had a good chat after, and it’s only when I got to my car I remembered that I didn’t actually pay her. I sent her a text to let her know I forgot, and that I was coming back to pay, she then let me back into the block of flats. Gave her the money and asked why she didn’t ask me for the cash. She said she remembered the money, but was so happy I walked through the door compared to the normal types she gets, she didn’t want to charge me. Have been seeing her weekly since then, again, with no money exchanging hands, which included over nights.
Bristolboy I wouldn’t look down on it. Give it a go, and see what comes of it. If she’s being genuine, she obviously enjoyed your company, and you make her otherwise boring day a bit brighter.
