It hardly matters whether it's a lover, a friend, or a blind date. Getting stood up sucks no matter how you look at it. And I can't think of any real valid excuse that would ever justify it (unless an emergency or something, though I'd think I'd be told about that eventually...).
I've had my fair share of the "fade-outs." You know the thing where a person responds to you less and less until they're no more. I've dealt with a few flakes too. I feel like being flaked out on differs from being stood up. Flakes don't ever really confirm plans. They kind of skate around the whole idea and when the proposed time comes, they're nowhere to be found or they tell you, "Hey I can't go because work tomorrow."
No, standing a person up comes after confirming plans with someone. After saying, "Yes, I will be there. I will see you at this time at this place. We will do this together."
That I've only had happen a couple times. Once by the last guy I dated. He was supposed to join me at a dance, though I never heard from him. To his credit, my phone was malfunctioning. I wasn't receiving texts, though I could send them perfectly. I chalk it up to miscommunication and hormones for the little dispute we had later once my phone was fully functioning.
My ex stood me up once and blatantly. Granted, we were going through a rough patch at the time but we had been dating for nearly seven months by then. I had asked him over for dinner one night and spent the day cleaning, going grocery shopping to get the ingredients, etc. Dinner time rolls around and I haven't heard a word. I start to make the meal, thinking he may show up a little later. Nope. There I was with two steaks and a bottle of wine for one.
When I asked him about it later that night, he skated around an apology. He knew we had plans and that he "dropped the ball on this one." His excuse was that he was too lazy. Someone needed to "light a fire under his ass" because he wasn't feeling like anything that night. Well, thanks for the leftovers.
Have you ever been stood up? How did you deal with it?
