Hi Donna,
Thank you for sharing your feelings with us, I can totally understand your view, those boys have driven you to a desperate place, and are making you and your wife suffer because of there own bigotry and ignorance, while I don't drink I do reach for the chocolate and bread bin when I'm down and regret it later which makes me worse, so I also feel you there.
I don't think it's my place to say one way or another whether it is the right thing to do to send the email to your family, I respect your decision on that, however I would like to draw a parallel to something similar I did last year, and how I feel about it now. My sister has not properly accepted me and like you pointed out actions or inactions say a lot, and her inactions wrote a book, I sent her an email of a similar tone to yours thanking her for her concern for my wife and family while we were going through quite possibly the worst period in our lives etc, it felt great to send that off to her, I was getting my point across and she was going to listen! Only I then felt even worse after a bit, and her reply rather than being conciliatory was bitter and her true feelings were exposed. I suppose my point is are you prepared for what may be the fall-out, and will you feel guilty about it afterwards i.e. will it make you feel worse inside? Some people have very thick skins especially people who sound like those boys, will it roll off there backs and help there poisonous agenda, but hurt you more, are there words that could be turn back around at you to hurt you later on?
I'm not saying one way or another whether to send it, just sharing my experience. I have followed your posts for some time and you have my support.
With lots of hugs
Nicole
