What do I text a girl that I had a quick but very receptive set with in person. But for whatever reason I’ve lagged 2 weeks to send her an opening IG message?

Usually if I don’t text them that next day that I’ve met them when there’s momentum usually any of the receptiveness dies out. I have great cold approach game(I consider my self close to advanced) but I find texting to be such a drag… I’m prob a 5/10 in this skill.

What would be a good first message after not hitting her up for a few weeks?
