Look at it this way.

Most “men” stay with a woman because they fear losing what they have.

What they should be asking themselves instead is this:

“Why am I willing to lose the potential of all other options in life for this one person?”

If you don’t have a rock solid answer for that, then she’s not worth keeping.

Love is weighing all your competing options, present and future, in the balance and judging them wanting compared to the woman you call yours.

What is not love: gratitude for being rescued by your woman from a life of romantic famine.
