Guy is slow fading after hookup

Hi all, recently met a fellow divorced parent online. He texted me everyday, multiple times a day for a week leading up to meriting. He drove 3 hours to meet me, we hit it off, and had sex. I was horny, it’s been a while, he was hot, and drove all that way so I figured why not.

He text me a few hours after the hookup. It took a few hours for me to respond back to that text. Later that night, he text me at midnight while I was sleeping, and I did not text him back until 11am following day. So since this, he hasn’t reached out to me. I reached out after 7 days of silence, asked him how life is going, and he said “Good. Super busy week, you?” It took him 8 hours to respond, whereas before he would respond right away. I text him back “same same” and that was that. It’s been 24 hours and nothing else has been said.

I’m a big girl, I realize what’s going on. I was thinking of sending this text:

“Hey so I didn’t really go into this with any expectations other than having a new friend, but I didn’t go into this really looking for a hit and run either, especially at my age. It was nice meeting you, thank you for the fun, and I wish you all the best.” Maybe a smiley at the end.

Is this ok to send or should I not even bother?
