Hello smart-girl ๐ this is an impressive comment you left me here.
The correlation you made between passionate love with obligation in your first point reminded me of what Adams and Munro (1978) say about levels of passionate love observed in newlyweds, which is lower than that seen in dating couples and those in a long-lasting marriage. They put his down exactly to the 'distribution of roles' which is higher early on in a marriage.
The boring details of day-to-day life can truly corrode emotions. As your point 2 examples illustrate!
You last point is a very insightful one. You approach the situation from an evolutionary perspective, but you also give space to subjective emotions. Because emotions are subjective. It reminds me again of what Tolstoy says "there are as many kinds of love as there are hearts". I suppose it is for each partner to understand the other partner's loving style. As you pointed out, some people love through words while others love through gestures :)
Glad to hear you liked my analogies ๐
Thank you for your kind wishes ๐ You too enjoy the week ahead creating, photographing, researching and practicing all your talents.
Much love to you always, always my dearest! ๐ :)
