On my wifes email that was left open on my computer, there were two open tabs up above the emails, where the tabs are lined up for all the emails that have been opened. The two tabs were for yahoo messenger and they both had a sexual name to them. One was mistress8777 and the other was moansofresh1209. My girls claims she has no idea how they got there. Is it possible that she is telling the truth. Can a person not in your contacts randomly try and chat with you and how does that work? My marriage is on the line so any info could help.
