Dont engage and continue with the 30 day nc. Stop adding her friends/family on facebook because it seems as if your trying to snoop on her and she wont like that and it wont make her return any faster. Just go about your life as if your not even affected by her departure and then she will return.
i have decided to move on. If she hurt me once and gave up when times got rough she will do it again. I can’t handle that. Maybe a cordial friendship, nothing more, down the road, but for now i am done
