“Yep, to me the joy of relationships is deep discussions...”
Good point. And that right there is the best “relationship” advice there is. If your “significant other” is incapable or unwilling to have those deep discussions, you probably need to move on and find someone else to spend the rest of your life with.
I recall my parents’ relationships with their siblings at times didn’t go that well. Some were lefties and incapable of having discussions... so at family events, discussion was usually avoided. Awkward times that should have been only fun and enjoyable.
I grew up in a family where you had to name your source, which over time became unnecessary for a couple of us as time proved that we didn’t need to since we only used firm facts and numbers and it was never personal but like other people playing a card game or board game, we were all searching for information and a better shaping of our views and reasons for them, and open to any sincere discussion.
Ravers and nutters and the nasty emotional arguers have always been people to avoid, for their personalities and because there was no value in a relationship with them, it would never go anywhere, and never become that rich, rewarding, lifelong relationship of growth.
