Exactly. Having your needs unfulfilled in a relationship drains your love tank.

When the person who has been draining your love tank suddenly needs a fill-up and finds out you are empty, then disaster is the only possible outcome.

It’s easy to care for someone when you have reserves.

But if she consistently demonstrates that she is not going to fill your love tank, then even if you care for her, it’s better to let her go, because otherwise at some point, something is going to happen, and it’s going to be far worse for the both of you.
