I think your text suggestion is fine. As long as you don't do anything majorly bad over text, I don't think that's going to be a rule in her decision if that makes sense.

I wouldn't focus too much on the technical aspects of escalation. That is likely to just overwhelm you at this point & make things harder then they need to be. Think about it like this. For thousands of years men have been escalating on women way before the PWF guide came out and game was even written about. You come from a long line of men who physically knew how to escalate (Otherwise you wouldn't have been born) It's hardwired in your DNA. The problem that you & most guys have is that anxiety/fear/overanalyzing holds them back from doing what is natural so rather then learning additional things, I think it's better to unlearn the things that are holding you back. Next time you're in a situation like this, just go for it & keep going for it. Ignore your fears & anxieties. A woman comes straight to your place because she wants to get fucked (The vast majority of the time) but she also has her own set of own limiting beliefs and fears. You need to help her overcome them. Once you get to a point where you get past fear of escalation. Then, it can be helpful to learn additional techniques.
