Maybe

Something happened and it reminded me of the past.
Thanks to this, I can totally relate to how my ex felt at a certain point of a time.

Shouldn't have stopped him when he said he wanted to look for that guy. Even if it was about pride. But I didn't regret doing it because I had my reasons, if we were to rewind it, I would still do the same thing. But really, most of the time, we quarreled not because we didn't want to understand one another.
But it's because sometimes, no matter how hard we try, we just can't.
