Besides apparently having the desire to unload a world of hate unto myself

...
I get intensely frustrated when two loved ones complain endlessly about the same problems (one has been doing so for decades). I have offered concrete solutions that have never been tried. Yet every phone call brings a recitation of the same complaints. Am I a control freak? Lacking empathy? Am I behaving like a man (the old trope about how men won't just listen to your problems but want to fix them which I always sympathized with).
Recently I've been trying to refrain from reacting or offering suggestions other than saying "I'm sorry you are feeling that way." But it is so damn hard for me to do and I end up getting frustrated again.
What is my personality flaw?
