Most men don't get that. They do just the opposite. One would think there are lots of things one can engage in other than romance, such as nurture a relationship with a pet or a hobby of some sort. But romance is essentially the only activity that stimulates so much energy in a person. A pet may be somewhat stimulating but acquiring objects won't help.
Objects are attainable.
Love is about struggling to attain the unattainable. A few days ago I was chatting with my haircutter whether it would be possible to spend 500,000 yen a month without acquiring objects, such as go on a trip or eat out. My haircutter was of the opinion that it would be difficult. Objects look fulfilling but are not. Yes, your heart has to come first.
