This is a vent but advice is welcome if you choose to give it.

For about a month and a half, I've (m26) been hanging out and romantically pursuing this girl. I really like her and fell hard and fast which is rare for me. We are intimate, sleep together, kiss and cuddle, etc. A few weeks ago we admitted that we would both be open to a committed relationship, but still needed more time and that's fine for me.

Fast forward to earlier this week, I suddenly felt off about it and I think I had a bit of a brain worm, but I told her that we should maybe not be as intimate because I feel as though I would be hurt if I ended up rejected by her in the end. Since then she has seemed a bit distant and I told her that I think I let my fear get to me but I think the damage has been done.
