I read up on your sitch during the weekend, I typically never post as its from my phone and just so hard to type out the longer responses .. especially with sensitive issues like what you are going through.
That vent you typed out ... no bashing nor 2x4's as yes .. this place is a safe house, those words/feelings most of us have been there, if you are going to release that I think everyone here would say ... yes... do that HERE, just never write them/show them/tell them to your W right now as it would only send her off even faster.
You have some of the heavy hitters this forum has to offer trying to help you see the forest through the trees, You have only been here a couple weeks, everything is just so upside down .. I remember it all to well. Like I have said before, I did not find this place till well after my BD .... I made a few mistakes before coming to this forum, and a few more during ... we all do.
Wonka hit it with her post, something I have been thinking about with you .... you came into a Self Defense class and we are trying to teach you basic throws in order to simply defend yourself ... however you seem to be convinced that talking your way out of the altercation is the best way, Leaving us to scratch our heads as to why come here for help and tell us your tactics rather than learn the basics, the fundamentals, use them and see if they actually might help your situation.
