thankfully, my life partner (I refuse to call her girlfriend) and I had been very good friends many years before we started our relationship, so when we started dating and subsequentially moved in together, it was a most natural thing, and since we started, as far as I remember, other than the typical "where's my left shoe?", "damn it, it's late, get up, we gotta get to work", "I told you to pick that up", etc. kind of arguments, which last no more than three minutes, we never fight or anything... we do disagree in some stuff, but it's nothing we can't talk over like civilized human beings
people have told us that type of behaviour is unnatural and might end up affecting our relationship in the long run, because supposedly, there's nothing like make up sex and all that fantasy bull**** people tell themselves whenever they try to justify their stupidity
I feel really lucky and blessed to share my life with someone who thinks and would rather use reason before an argument
