Re: did I miss escalation, how to proceed
It all depends on your attraction level on your first meeting. We'll probably be needing a bit more detail about the night you guys had rather than your texting.
If you attracted her mildly, you need to continue on attraction via texts before asking her out on a date. If you got attraction covered, you're probably safe to snatch a date but she might still flake on you because this time you might not have built enough comfort. Some girls wants to build comfort on a date while other girls wants to feel safe & connected (comfort) with a guy already before going on a date.
Attraction = "I want this guy but I don't know him."
Attraction + Comfort = "I want this guy."
It's not about who I was or who I'm going to become.
It's about who I am. Do it right here, right now.
