Once they make a decision, they then continue to second guess that they made the right one. Not a big deal if you are deciding which restaurant to eat dinner at or what movie to see, but when it is a major life decision (dating, marriage, children) it really sucks to be around them. Everyone has doubts that they've done the right thing, but you can't change the past. Stand by the choices you've made, live in the present with an eye to the future, and enjoy what you have rather than lamenting what you think you gave up.
They also seem to expect people to just magically know what it is they want. They don't tell you their expectations and then get upset when you don't meet them. How in the heck are people supposed to know what someone else wants if they never tell them?!? The rest of us don't have those mystical INFP powers that allow us to "just know." You'd think they'd take pity on us and just tell us what they want rather than make us guess.
Sometimes I just want to curl up my pudgy little fist and pop someone right in the kisser while shouting "GET OVER IT! IT'S NOT ALWAYS ABOUT YOU!"
LOL! Don't get me started. But since you asked...Dithering about a question to the point of being unable to make a decision, then ultimately doing nothing. They then moan about those non-decisions as if something was taken from them. Lack of action is a decision, even if they don't want to see it that way.
Actually, I felt guilty about my post so I had to balance it by making a post in another thread.
I don't think you needed to feel badly about this at all.
