If as she says she's not interested in me or a relationship with me anymore why does she do this to me? Why press my buttons like that.
Cause part of the script is to make it YOUR fault.
You may have always taken the blame for her choices in the past and why would she want to admit any fault at all.
If she can make all this YOUR fault it is much easier for her.
She is going to have to go all the way through this cheesless tunnel. There is no avoiding it. Let her GO. The only way is forward - there is no going backwards now.
