Adaptability

Even if it exists it's always in the time skips and we only ever catch a glimpse of it. The main reason for this is because it's "normal", The exciting part of the hero chasing the heroine(or vice versa) has ended, In the beginning, their love for each other was something new but now it's become an everyday thing, They have adapted to the new scenario they are in. Which isn't as exciting and fun to watch to be brutally honest.

Humans are regarded as social animals and emotions and relations mean a lot to us. But in some ways, we are very cold-hearted and desensitized. One of the reasons I say this is because of our high potential for adaptability which is a boon in terms of survival but a bane in terms of relationships. With regards to any situation no matter how grave humans just adapt to it.

Let's take the most famous topic ever for this case "LOVE". The reason phrases like the one above is false is that a person never knows when they adapt to something, You may adapt to like alcohol or you may adapt in a way where you are sleeping more, It's a natural concept. But when it comes to giving false hope of something you are sure of only for the moment it's kind of a shitty play, to say the least. This Adaptability in my opinion is one of the main reasons for relationships going bland after a few months and also Divorce.

There is something of a rose phase to every relationship where its all fun as the consumers(Of love) are just experiencing the affection and happiness but soon down the line just as anyone does they start adapting to the situation, after this point it's an uphill battle as usually most couples cant adapt and break up seeking the infamous 'rose phase' again, this is clearly a vicious cycle and according to me can be broken by bracing yourself for the adaptability earlier on.

To add to the reason as to why this causes the above tragedies (fortunes for some: divorce lawyers, gyms) is because the aspect of loving each other changes from something that's new and intriguing to something regular. This is one of my craziest arguments regarding love at first sight or anything that happens in an instance in general, how are you so sure you aren't making decisions based off an impulse? A decision that may cause a considerable amount of emotional turmoil down the road.
