Phoebe, I don't know of this is good advice, but sadly it helps me. I keep a list of the things I won't miss about my STBX. When I miss her it helps me re-read that.
I also keep a list of things that I am grateful given my new life and re-read that often.
(I also have a list of things that I think my STBX won't miss about me - for those I plan to tackle one at at time when I am ready)
I also have a Testament I read daily out-loud. Here's mine which I have evolved over the last 6 months:
I must accept my marriage is over
Surrender to what is, let go of what was, have faith is what will be. -S Ricotti
Even though I feel depressed about losing the person I thought I was going to spend the rest of my life with, I deeply and completely accept myself
Each day I will live in the here and now and consider it a blessing to receive and give God's goodness daily.
I give thanks to have this opportunity to truly learn myself and invest in my emotional and spiritual growth.
The hidden blessing is all the time I now have to cultivate my new life and strengthen my relationship with my Daughter, Family, and close friends, and make new meaningful relationships
I will put in the hard work to become a better person and one day meet the partner of my dreams
When one door closes another will open.
