Sorry man, it's not supposed to sound easy. It never is... But you have to be strong for her, you have to put her ahead of you at a time like this. You need to understand that there is a reason why she isn't wanting to agree to an amicable relationship right now and that is because this is tough for her to and she is perhaps reconciling in her own womanly way. (No I don't know what that means, nor do I understand them, but I do know that it's best to give them space at times like this.)
You know that stupid old say. "If you love them let them go and if they comeback it was meant to be and if they don't well...."
I repeat, it is NOT easy. It is neccesary, for you, for her, for peace of mind and for any hope of you two to ever have a decent relationship sometime in the future you need to give her space for now.
Like I and so many others have said take this time to fix, work on and build your future. Stop dwelling in the past. PRAY my friend, PRAY and I and others will be praying for you as well.
Yeah, I was thinking about something along the lines of a month to allow her to get her head together and all that. I do not expect things to come or happen overnight. That's not the way it works.
