As a business man it is YOU who is being naive and silly about having a SIGNED agreement...
She would be nuts to not have an agreement signed. She sounds like a better business person than you. Is that why your business failed?
You should know better. It should be YOU that is leading on getting the correct documents signed and in order. You are fighting her on an issue that she is NO DOUBT correct on.
You really can't see that this has NOTHING to do with trust?
You think it is a matter of trust for her to love you again.
The reality is that it is a matter of her FEELINGS. She doesn't feel love for you. You making this about her trusting you isn't true. There are people who come on this site every single day and still want to be with a person they obviously don't trust. It is about FEELNGS... All about feelings..
