Those are difficult feelings - you want something from someone but realistically you know you aren't going to get it. And if " letting go " were that easy ! Six months is a short time , the feelings do fade as time passes. You have a good T to work with with the complexity of this. I somewhat had this with my Brother - " He betrayed me / I trusted him / he should own his behavior / how did I let him do that?! " The feelings only hurt me. Sending you hugs.
