About 16-17 years ago, I contacted my husband's T. He has ADHD and depression. He kept talking about how everyone and everything was against him and threatening suicide. So I called his T and told him. WORST thing I could've done to my husband. He felt totally betrayed. Ended up having to meet with his T and then repair our marriage. He no longer sees a T anymore and he's been good since.
Husband has "threatened" to call my T, and I've always said "go ahead, I have one coming". We joke about this now.
If you have discussed it with your spouse, and they are in agreement, I think it's ok to contact their T.
Your spouse's T is obligated to your spouse only. Anything you say to them, they will disclose to your spouse.
