Dear Abby,
My husband"Nick" has been acting strange.I think he may be having an affair.
Until recently, he showed little interest in our family dog "Trixie". However, lately he has offered to walk Trixie every night. Some nights they are gone for two hours.
Last night, when I went outside to put something in the mailbox, I found Trixie tied to a tree across the street. Nick was nowhere in sight.
What do you think I should do? ---Worried in Washington
