But she isn't moving on... she's trying to reconnect while in a relationship with someone else.
I agree with Lite... she's looking for a backup in case her current relationship goes sour.
I seriously doubt she was giving this guy much thought until her current relationship started getting shaky. Seems more like a selfish move to me.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
