Seventeen

Brian and Justin have been together for seventeen years, well, more or less: seventeen years have passed since the night of their meeting, the one in which Gus, the son of Brian and his friend Lindsey, was born and since then they have been on and off regularly.
Gus, however, is willing to do anything for his relationship to be as smooth as silk, but he has just moved to Pittsburgh and the only thing he is sure of is that life is a mess and this, in essence, is the only thing on which father and son agree.

I thank Lorie for correcting the translation, allowing me to publish it here as well.
Without her help, you would have found many errors, inaccuracies and ways of saying that in English make no sense.
Not to mention the pronouns I had lost along the way.
