Beautifully said. I was with my late husband for 13 years. Our new phase lasted a really long time, and he was super-romantic, and full of grand gestures. So, when things moved to the "boring" phase, I really struggled at first. I thought he'd stopped loving me, or that, at least, he was sick of me. I finally understood what was going on, learned to just ride that phase out, and learned to ride out the lows and cherish the highs. Reframing the way you think of it all can help so much!
