How big can love in a relationship grow then? Like if I quit all my hobbies and quit my job and just give all that time and resources to my husband, will our love get very big then? Or is there a limit after which it is saturated and extra resources don't mean extra growth for the love anymore? Maybe those extra resources can then go to an additional partner without the original partner loosing anything?
I don't think love can grow infinitely that way. And I don't think one should give all their resources to a relationship even if they are monogamous.
I never said it can grow infinitely that way. I never said it can grow infinitely at all. Nor do I think that one should give away all of their resources to anyone. Especially if you have kids/parents. And just so we're clear, none of what I'm saying is meant for advice on what anyone SHOULD do. Adults are free to make their choices. I'm not the morality police.
As for how much it can grow... I don't have an answer. I don't think there is an answer that applies to everyone. Some have large capacities, and some have small. What I do think, is that everyone's capacities can be looked at like a pie graph. We all have our 100%. For some, everyone that fits inside has equal portions, and others have varying. Do you love your husband more than your friend? If so, you just measured love.
