I left; you didn’t need me.
A long time ago I learned not to explain things to people. It misleads them into thinking they’re entitled to know everything I do.
If you aren’t their first choice now, what makes you think that you’ll ever be? A promise is a comfort to a fool. “I love you” and “I’m in love with you” are two totally different things. It’s easy to love someone and feel affectionate towards them, but to be in love with someone, their habits, their lifestyle, their thoughts, their reactions - that’s something entirely different and rare.
