This is just another step in the process of moving forward.
When we first start our journey, we look at ourselves. There is a sense of guilt for awhile at how we contributed to our demise of our relationship.
We beat ourselves up over it.
We then work on ourselves and over time... we shift to the other side of the spectrum. The side where we feel worth it and become "done" because our spouse has clearly not put in half the effort we have.
And we move forward.
Like AC said, it is a rollercoaster and eventually you will come to the middle where you still feel like you are worth it.. but you no longer feel anger or hurt anymore. The expression "his/her loss" doesn't even matter.
I think you made a good step. I remember the phase you are in and it was healthy for me.. for awhile.. Then I found myself feeling "superior" to my w and that ended up bringing on more anger.
Not saying this is you or will happen to you.. just saying to keep your heart open.
Great work! Keep on Keeping on.
