It sounds like an ocd thing. My husband has ocd and some days he just can't leave the house it's so flared up. It sounds like your husband was trying but he was way to stressed. I understand your frustration and yelling. I really believe in therapy for both yourself, your husband and couple that are all in the same practice that talk to each other. At the very least both you and your husband should be seen in the same practice NOT the same therapist. If you think you have mental illness please get evaluated. If you do have mental illness it needs to be treated to have a healthy relationship.

My therapist has told my husband several times if he keeps doing X I will leave him and not bat an eye about it. Remember you are not his treatment team your his husband. You suck at being his treatment team. You can be supportive but you can not replace his therapist or psychiatrist. You may want to sign a statement saying you can talk to his therapist and psychiatrist in case of emergency.
