I am really worried about you. He left you at the mall before he told you he was leaving? This is not right and you do not need to take this kind of behavior. I am SO glad you have family nearby (brother) that can support you. I was wondering how you managed to get home. I'd like to know how he explained his behavior to your kids...leaving mommy at the mall.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
