Insecurities: we all have them, no matter how beautiful we are, how successful, or how much we fight them, everyone has their own insecurities. They're masterfully specific too, I truly believe that no two insecurities are alike. Maybe on the surface they come out as a certain type of jealousy, but their origin always holds its own unique tale. They could stem from our childhoods, from the way a parent has treated us, from an event on a school playground, but they're intersected with our innermost memories and somehow locked in our hippocampus forever.
In this Reddit thread, the original poster (OP) is a woman with insecurities, ones that stem from her childhood, regarding her sister and her husband. They have a story, and back in the day, her current husband used to have a huge crush on her sister. Sure, people grow up and grow apart, and something like this could be harmless. But what if push comes to shove? What if there are more and more skepticisms regarding their relationship, and the insecurities are proven right when your own mother denigrates your marriage?
