With er coming back, she still has feelings for you. However, she wants her cake and eat it Two. She wants to be her own free bird and not two birds of a feather but Yet... Keep you always close even if it is in her back birdie pocket.
Block her, don't reply to her if you want to end the madness. If you keep it going, it will always be a Full circle problem pattern and Nothing will ever be accomplished, not even You and your heart moving on.
Good luck. xx
