<human>: Provide a brief overview of the text.

I've been dating this girl N for a month and a half and we've gotten to know each other pretty well. I'm away on vacation for the week but last Thursday before I left, she came over for a couple hours and texted me afterwards saying "I'd say I'll miss you but I hope I get to see you on Monday" with a smiley. I got permission from the folks to drive back to see her and when I told her she texted me "Yaaaaay" 

I texted her on Monday that I was back in the area and we exchanged a few messages the last of which was me telling her to come over when she was finished with work which was around 6. Sent a follow up text and hour later "text me when you're on your way!". She never showed and I've held off until now contacting her.

I know some people will tell me to cut my losses now, but I need to at least make an attempt at closure. Any ideas how to reach out without demanding an answer or sounding clingy/insecure?
<bot>: Date flaked on a hang out she was proposing a couple of days earlier. Talked the day of but got stood up. How do I reestablish contact without sounding demanding/desperate?
