Feeling stuck in the pain that has come from my decision.

I left a 1.5year relationship because I wanted commitment and monogamy and he didn’t yet. We loved each other very much but were on 2 different paces for the future we wanted.

I feel so sad because I don’t want it to be over for the fact that I enjoyed our friendship and I really enjoyed having the support of a partner in many ways.
But I was unhappy very often while dating him because I was betraying myself and what I really wanted which was a committed relationship. He was still sleeping with other women and that was so hard for me to be ok with or look past.

Im so torn between my thoughts. How do self coach your way out of torn thoughts?
I am currently doing: Thought downloads, models, bridge thoughts, opposite thoughts, etc.
