Ask Allison: I’m in an unhappy marriage and can’t afford to separate. Have you any tips to help me stay sane?

Question: I am very confused about what to do. I am in my late 40s and have young teenagers. I have been unhappy in my marriage for a long time. If I am honest, I should never have married my husband but I got caught up in the fact that all my friends were getting married and it seemed like the thing to do.
