it is hard isnt it. a tear free day is my goal. had a few myself today. i am sad for the same reasons as you. i read something about unconditional love, and how it is a choice. i am sad for what is gone. no matter what my W chooses to do, i want her to be happy. because i love her. unconditionally. i think you feel the same about your H.
choosing a path for yourself is scary for me. out of my comfort zone. codependency svcks. you are doing amazing. its okay to cry. especially if you can figure out why. sounds like you know why. good job.
