So I'm about to graduate university and move back to my home city. I've been having some success this year and doing much better with women than I have in the past ( style, health, confidence and attitude are the big contributors). There's this absolute smoke show back in my home city who I went to high school with, I never thought into it because we were both in relationships but now I looked at her Instagram and she is absolutely stunning compared to what I'm used too. Anyways here is where I am stuck.

I responded to one of her Instagram stories about her asking for a PT recommendation in our city. I responded with a good one and we get to chatting for a lil and I leave it after about 6 messages back and forth. So now my question is, how to I proceed now that I am actually considering pulling this off. I'm not a DM guy so this is all uncharted territory for me. I'm a good enough looking guy where girls hit on me or I'm able to flirt with them in person but this whole DM thing is new to me. So how I go about hitting her up again when I get back? Any advice is appreciated.
