When to end a highly invested LTR

[Marty]

As a matter of fact, if you're good enough in person, you don't even need to be sexual at all over the phone. You just text, set up the meet, and go!

Sound advice as ever, Franco!

You could go with something like:

I'm not looking to get into any serious dating myself, so hopefully I didn't come across that way. I did enjoy your company, however! If you'd like to grab a drink and have a relaxing evening with me, then the offer still stands. What do you say?

I like this very much, actually; it's attractively persistent. I copy-pasted it and sent it verbatim this morning.

Honestly, my worry with this type of text was that I'd have a chance of coming across as seeking a platonic buddy. But in view of what you wrote above regarding in-person behavior, I see that's a straightforward fix!

Fortunately I was quite warm touching her and gave strong, yet flirty eye-contact. I cheek-kissed her at the end, which on account of her thinking I was aiming for the other side turned into a lip-kiss, much to her flusterment and my own amusement!
