Love doesn’t come & go like the rain.
Yes, there are different (actually infinite) kinds of love, and yes, love can change; it can grow stronger or weaker.
But at the end of the day, at the same time, even though there are varying degrees, if you love someone, you love them.
It doesn’t ‘come & go’.
You either love them, or you don’t.
This, of course, is helpful to remember when you momentarily feel like you don’t, or you’ve forgotten how much you do.
