So I met this girl on tinder in 2020, slept 3 times that year, was not serious then we stopped talking for 9 months. I wanted just to be friends with her this time and didn't put much flirty vibe out there, I wass more friendly but I still find her attractive and then 3 weeks ago we drank at her place and had sex. She told me that she doesn't see me as anything more than a friend but she told me that she doesn't regret it that we had sex. So, I think we could have sex again in the future. How do I message her, I thougth it would be a good idea to stay in touch, I will be in a different town for a few weeks? . What do I reply here, to get her more invested or switch to a more flirty vibe? I translated this to english. Do I leave it at that or do I procced with something?

Me: Heyyy -Name
Her - Heiii -My name :D
Me: We haven't talked in a while. I was studying and a lot of other things happened. I will be -different town, for a little while now. You?
Her: Yes it's true. How's it going with the course. You're probably practicing it now. :)
Her: I am good. :) as usual.
Me: :) Something happened so I will have practice hours tomorrow.
Her: wiii super 🎉
