Oh falling,
I know exactly how you feel - cut off, isolated, betrayed in a way, hurt, confused, angry? Here you are, the one person who would be there by his side to help and support him, and it feels as though he has turned on you, doesn't it? I feel so much for you. Accept that you have absolutely no control over what is going on right now. Accept it and let it go while you pour your energy into managing the other things in your life. Make all the decisions to finish your house on your own if at all possible. You just cannot rely on him right now. I am so sorry you are going thru this, I know it must feel devastating!
Just my husband not signing a release for me to talk with his therapist/doctor is devastating enough for me. I imagine he would do the same thing in this situation.
Are you seeing a counselor?
Hugs,
