Relationships are always complicated, I've never had much luck with them and with my wife at the moment, I have a daughter and a son, we've been together for 9 years (since 2015) and we love each other, I believe that, but even so, it still feels like something is missing, perhaps a little more affection and sacrifice from her too.
I don't like to measure who does more of this or that, it wears down the relationship too much, but I always feel that I sacrifice more, that I have to keep quiet more often to keep the peace... it's strange.
That's what love is, it's good and bad at the same time.
