I went on a date with a woman for the first time (im 30). When we spoke, I told her I wasn’t ready for anything serious after a long relationship, and wanted to take it slow.

We’ve met 3 times, and on the third date, we slept together. She booked the hotel, champagne etc.

She’s messaging daily, saying she can’t stop thinking about me. I like her, and I'd like to continue seeing her but I don’t want anything serious right now and i dont have a feeling she is THE one anyways.

Was I unclear about my intentions? How could I have been more straightforward? And how can I let her down/rectify gently? I don’t want to hurt her feelings, but this is all new to me, and I don’t want to be mean..
