Guys, Recently My GF shared her desktop with me and I noticed that her ex boyfriend had sent her some message on Skype in the Chat Notifications.I asked my gf whether her ex had messaged on Skype and she said No . I told her I have seen her Chat Notifications though i didnt read the Instant messages . She then deleted her Chat History and said that the ex's mother needed some important advice and her ex had IM'ed her to thank her for the help. Today I asked her to show me the Chat History and she said she had deleted the history right then . Should I continue to trust her blindly ? She has repeatedly asked me to have faith in her .
