The feeling of love, like all feelings, is something that comes and goes, but we can act with love forever if we so choose.
We can choose to behave in a loving way toward others regardless of how we feel.
Our feelings are unreliable anyway.
They are tied into a variety of factors, many of which are entirely out of our control.
Our actions, on the other hand, are ours to choose.
We get to decide what we will do, how we will do it, and who we will do it for.
From moment to moment, day to day, we get to decide how we are going to behave.
Our feelings and our actions need not align.
We can act in a way that is loving, caring, and compassionate even if our feelings are something altogether different.
This does not mean that we are disingenuous.
It simply means that we are generous.
