Are relationships 50/50?

I’ve heard Brooke talk about how relationships are 50/50 – like life in general is 50/50.

What does that mean in terms of relationships? Does it mean that 50% of the time when I think about my partner/my friend it’s not going to feel great? And how does ‘being a good mate’ and ‘brainstorming love’ fit with this concept?

Love being in SCS – thanks so much!
