9. Red flags are red flags for a reason
If you can spot some bad qualities or habits in the first place, don’t ignore them just because you became so fond of them. If there is a black spot out there, it has to have some reasons behind it which you will have to face sooner or later. If you cannot handle those problems, don’t let those handle you. You will never be able to live at peace with this kind of people. Just leave them right away or else you will have to regret later when there will be no option to undo things.
