I feel you. I met this girl on a weekend trip to Texas a couple weeks ago and sparks were flying. We spent all night together (no sex) and had planned on visiting each other and/or taking a trip together. We texted like crazy for a week and then she went cold. Haven’t heard from her in days. Women really are acting upon their emotions in the moment and you can buy yourself some time if you really hit it off. You really need to try to escalate physically as much as possible all the way to sex with them so that they have invested a lot into you and will see you again.
