Thank you for writing. You’ve already taken an important first step by reaching out for some help. The next step is go back to the therapist who was helpful to you. He or she already knows your story and you’ll be able to pick up where you left off.
Therapy for a significant depression is rarely a one-time episode. Think of it as layers. You got through the most difficult one. Now it’s time to work on the next. You can draw comfort and hope from the fact that you did get better. You will again. This time you didn’t sink as low so it will probably be easier to find your strength again. Your therapist will also be in a position to help you figure out whether there is any reality to your husband’s position and whether the marriage is salvageable.
I do have my doubts. From what you wrote, your husband is not approaching you about what he can do better. Instead, he is blaming you and trying to isolate your from your family and community – and even your God. He’s also putting the children in the painful position of being in the middle of your divorce. If he were serious about making the marriage work, he would be taking some responsibility for the break down of your relationship (both to you and to others) and would be asking to join you in your therapy to do some couples counseling. Most important, he would be considering his children’s need to have two parents they respect instead of trying to get them to take his side.
Meanwhile, I hope you have talked with a lawyer about what your rights are. You may be able to limit your husband’s contact with you and what he can say to the children. I don’t know the laws of your country, though, so I caution you to seek out legal help.
Finally, ask your therapist for a referral to a local support group (or an online group) for women who are having similar difficulties. I think you will find it affirming and helpful to have the support of others who know what you are going through.
I wish you well.
