A very good and old friend of mine who I haven't seen in ages (due to the pandemic plus years of her flakiness) messaged me last week to arrange to meet up today at a park and she has just cancelled. I have another friend who does this. When either of them arrange anything I always know they're going to do this to me. Why do I bother? The thing is, it's usually them who contact me to arrange to meet up, so it's not like I'm the one pushing for it, then they cancel at the last minute. No reason, just sorry, can't make it anymore. We can find something else to do, it's fine, but it's just annoying as we could have made other plans with someone more reliable and my DC are disappointed they won't see their friends (DC of my friend). I was in two minds whether to tell my DC what we had planned today because this friend has form for this. I only told them yesterday, really wish I hadn't.
I want to know why people do this? I have a busy life but I manage to stick to plans I make 99 percent of the time. I really like these two friends as people but I'm just so sick of being treated like this.
What should I do? Just put up with it, like I have been for years and always know that any plans with these people are more than likely not going to happen? Or stop making plans with them?
