It's making me feel less insecure and more F*** Him!
Well congratulations for starting to frame yourself as the prize instead of framing him as the prize and leaving your sanity and happiness in his hands ~ He who has yet to earn any of that from you.
Let us know how it goes.. if you actually get together on your "date." At this point it doesn't matter if you contact him to see whats up, if he doesn't respond then you know just how little he does value you. Don't believe any bullshit excuse either (if he contacts you after the date night and apologizes) It takes two seconds to text someone with "don't be mad but I can't make it tonight. Will call you tomorrow..."
