Dear Annie: My husband’s sister “Kelsey” filed for divorce a few months ago. Her soon-to-be ex-husband kept in touch. He told me that Kelsey had been cheating on him with the guy she is currently seeing. I didn’t want to believe him, but in the past few weeks, I’ve discovered that Kelsey has been lying to her parents, her brother and me about nearly everything. Her new guy has a DUI and lost his license. He has a child from another relationship, doesn’t work and rents a room from his brother. Kelsey has been paying for his plane tickets so he can visit her. Kelsey told me she was filing for divorce because she couldn’t deal with her husband’s child from his first marriage. Now she is jumping into another relationship with the same set-up. She is convinced that “it’s different.” Her parents are unaware that Kelsey is planning to move two states away to be with him after she graduates.
