Made a mistake with ex, left it long enough to forget the bad bits but now really regret getting back together. He's quite attatched to DS (we were together a few years) and was so glad we were back together.
I was but after a few weeks it's hit me like a juggernaut in the face. I feel terrible. He'll be really hurt and mutual friends who were already shocked we were back together will think I'm the wicked bitch of the west 
AHHHHHH.
