There’s a pastor speaking on TV and he made a point about relationship that really stuck with me. He talked about how people in puppy love have a tendency to admire traits in their partner that becomes annoying/obnoxious when they’re married. It starts out as “He’s wonderful! He’s so laid back and relaxed!” But then turns to “he’s so lazy!!” After being married. It can start as “She’s awesome! She’s such a go-getter and she knows exactly what she wants!” But turns to “She’s so controlling and picky!” When married.
Basically, his point was people have a tendency to idealize their partner if God isn’t their #1. We start seeing them as “our perfect other half” which will lead to disappointment one way or another eventually.
