As the title says, but here's a brief story of what happened

First two dates - Mostly conversation, some flirting/banter, light physical escalation but no kiss

Third date - She invited me to her place, escalated very confidently, spent the night, left the morning with a long hug, a passionate kiss and she telling me "I'll hopefully see you next week". One thing to note here is that, as I picked her up from the couch to go to her room, she had a LMR saying she doesn't want to have sex. I'm not the pushy kind and very conservative when it comes to this, so I did not push for it.

After 10 days, yesterday she texted saying she didn't feel a spark.

Here is the exact working:

Hey OP, so it’s been super fun hanging out with u and everything but to be honest I don’t really know if I feel a spark. Like I think your a really cool guy and id love to be friends but I just wanted to let you know where I am

My reply:

Fair enough! I appreciate you letting me know. And sure, sounds good to me!

Fair, but she is physically attracted to me as she always complimented my looks, biceps, always told I'm very popular/smart/good looking etc. Couldn't keep her arms off me the whole night we slept together, always feeling my chest/abs/biceps.

She was/is probably looking for a relationship but I probably acted like needy bitch over texting in the last few days. I'm certain she doesn't hate me or is repulsed by me but probably doesn't see a long term relationship with me, but, I was wondering if there is any way to turn this in the direction of an FWB or casual relationship.

I'm not holding my breath on this one, but, since it probably won't go anywhere now(and the "friends" part is very likely a soft rejection rather than saying she doesn't ever want to see me), I want to shoot my shot at having an fwb.

Any suggestions?
