Hi Aug82,
I am so sorry to read your story, I can see why you are feeling so untrusting and devastated. It sounds like the breakup is quite recent?
Your wife treated you badly. It's okay to grieve for lost dreams, feel betrayed, angry, sad and any other emotion that arrives for you to deal with. One of the emotions that will arrive is acceptance, hang in there. Your ex's bad behaviour is not for you take on. You know what sort of person you are, I bet you have plenty of great qualities that this woman has forfeited, her loss.
Don't be too hard on yourself and give yourself the space and time you need to heal.
It's no wonder that you feel unable to trust at the moment. It's sad that your marriage worked out this way.
This is a safe spot to vent, let us know how you are feeling, no judgement on this site.
I can see why packing up and moving is attractive. But then you may find your self alone in a strange place. Do you have family and/or friends around to talk too and get some support, they will probably be more supportive than you would think. Are you keeping in touch with your psychologist and GP?
