I have been married for 25 years to a man who is responsible, kind, a homebody and God-fearing. A month ago, I discovered accidentally that his ex-girlfriend in high school and college, who is also married now and live thousands of miles away, sent him a message in Facebook to be his friend. Being a gentleman, my husband accepted her invitation and they became friends. From then on, they kept exchanging messages. I was able to read them without my husband’s knowledge. The messages contain just updates on their lives the past 30 years—no hanky-panky except phrases from the girl like “take care of yourself,” “be safe when you travel.”
