As someone who has been there, I can say it will get better if you both understand and want to change!
We went from having sex 1/2xs per year to having sex 4/5xs per week. We did it through communication. Our problem stemmed from all the norms. Death in the family, depression, age, unmatched desire levels. Mostly me wanting more and him acting as though it was a burden.
I found out his secret desires. As vanilla as they seemed to me, I went all in. Strip tease. Check. Anal. Check. Positions that use mirrors/cameras/light so he can take in every visual I was offering up. Check. Treating him as a king. Check. The littlest thing that made the biggest difference was I started DATING my partner again. Emotionally checking in on him made our love that much stronger.
I hope my words offer comfort and useable advice.
Sounds like you started appreciating each other again. I got married 6 years ago.
I started working nights 4 years ago, My wife works normal professional hours. We used to be two passing people in the morning, she would pick me up and that along with 4 hours in the evening to wake up, eat, get ready for work, that was our alone time for 3 years. it takes some effort to rekindle, but its so worth it to re fall in love with that someone special. Dating, as in going out on a certain day together our day, special outtings etc.
