At what point do you consider something a lost cause and give up? At what point do you make a decision to not try anymore?
If someone makes plans with you over and over again and cancels at the last minute over and over again, I think that’s a pretty good sign they don’t care about KEEPING plans with you. It’s a clear sign they don’t respect your time or your feelings so why continue the pattern?
Giving up depends on how close you are to someone, too. If you are building a relationship with someone, being blown off over and over again is an early sign of things to come. If you decide to let it go, there may be a bigger fall waiting in the wings. Been there, done that.
Everyone has to decide for themselves what their own giving up point is. It boils down to how much of yourself you’re willing to give up for someone else. Respect is a big thing. If someone doesn’t have that for you, it’s sometimes best to cut those ties because the chance of things changing aren’t very high.
