Walk, just a few thoughts to share. My counselor recently suggested the following regarding the divorce conversation. First of all use the term, 'I" , and keep it brief , no explanations are necessary, know what you want and be prepared to state it. Be prepared, speak to your attorney first, research your financials. It may help to speak to more than one attorney before you decide who you want to represent you.
Let a close friend know you plan to discuss divorce with your husband and tell her if you do not call her at a designated time, to call the police. My counselor voiced concerns that there is probably a lot more that I do not know about my husband, and be prepared for his anger. It may help to have a bag packed and an exit plan for you and tell him he must leave.
My counselor had advised me when speaking with my husband, state, " I care about you but I also care about myself, and I want a divorce."
Good luck, my friend. I know how painful and sad this is. I have to wait until September for the divorce discussion.
