In real life, making snap romantic decisions is the EASIEST THING IN THE WORLD. Fucking ANYONE can do it. It doesn't take some magical, transcendentally alive character to suggest getting hammered on vacation and having sex in your Airbnb kitchen. That's the easiest part of life. And guess what? People who are organized and thoughtful in their day to day lives are also legally capable of making fun snap decisions. Real humans don't exist on a sliding scale from "stable and unromantic" to "unhinged and ROMANTIC." Being a hard-working non-fuckup doesn't preclude someone from understanding the concept of "fun" and pursuing it.
Being a reliable partner takes WAY more work than deciding to do an occasional fun thing. And by "reliable," I obviously don't mean "perfect" -- we all have our issues and suck at things from time to time. But striving to be stable -- doing the dishes when the other person's had a hard day, entertaining each other's families, not being constantly late to meet the other person, letting the other person vent without judgment, refilling the gas tank when you know the other person has to be somewhere early in the morning, even remembering to buy friggin' paper towels -- is NOT antithetical to "being romantic." It all requires more thought and demonstrates a deeper level of kinship than, say, pushing someone down a zipline and screaming "LOOSEN UP, PUSSY!"
