If not, then she should go to counseling alone and leave you out of it. She clearly needs to sort out her own sh*t first before you can come back into the picture.
You're wounded and hurt by her actions. Would you want to attempt to go with her so soon because she MAY be willing to work on the M? As evidenced by her actions, she still does not know what she wants. And she needs to know what she wants and not have you to fall back on in case she messes up. Let her truly miss you. Let her truly realize how life will be without you. Let her fall and get hurt.
The way I see it, she is still using you to cake eat. Telling her to take a hike takes away the cake.
You yourself need to heal and get strong first. You are capable of it, bud. I have felt it when you chime in on my sitch.
