I have three children but yet I'm not having good terms with my husband. We will complete 15 years

hey dear, i know what you must be feeling now after 15 years and 3 kids... i am sure you have tried, but would you like to try a little more? you both can try going to a counselor one last time. if nothing works, maybe you both should speak to a lawyer and understand how best to sort the legal proceedings and move on.
