Love and Hate, pain and pleasure all follow the same path within a human being.
Toss in the constant dopamine drip of smartphones, and we have quite a few people complete over stimulated to the point where connection if made will be brittle.
This is why folks need IMO pipelines of people (think like multiple apps on a smartphone), and when something goes cold (wrong) that is why people break, over react, or worse over personalize something that wouldn't have phased someone if the same thing happened in the bars in the 1990s.
I was eating a meal at an Italian restaurant bar this past weekend, and was talking to a pretty amazing Gen X woman. She ran Denny's and other restaurants (quite a few in fact) and she stated starting in 2006-2012 nuance was lost with people. You had to treat everyone with kid gloves and it sucked.
Now why this bring up? Spending time working and working a relationship in love and friendship, requires work, nuance, patience, and balance.
None of which you get when you become imbalanced in the areas you call out. The woman went from a drink to an appetizer and a drink and then took her order for her and husband to go.
We both left a little happier (given the slow service), and that took maturity. Something quite a few people lack anymore.
