Let's make a list of ideas here. I'll start:
I will purposely remember falling in love, and nurture those feelings now!
I will put his needs equally with my own, and choose actions from that vantage point.
I will stop assuming my husband isn't thinking about a topic that's important to me, even if he doesn't raise that topic. (I can bring it up. I have been happily surprised to find out just how much thought he had already given.)
I will share my own fears and uncertainties more. I don't have to take care of it myself (despite learning that lesson quite well growing up); we can do it together.
Since our goal is to be a healthy, happy couple, I will . . .
(Now it's your turn, readers.)
