You need a bit of "vavoom" in your personal life.

Something that makes you happy, makes you smile.

And I mean something separate from your husband that you do that brings you joy, so that whilst you are working on areas that need improvement in your marriage, you have an "outlet" of sorts so that your energy isn't focused 24/7 on something that may take some time to fix.

Maybe try your hand at a completely different hobby that you've never done before. Joining an art class might help. That's a far out there suggestion but used to illustrate what I mean.
