Welcome to the boards. I saw your post on SDFoundGirl's thread and wanted to pop over to say hi. Our sitch's are nothing at all alike but I like your writing and what you have to say. Just saying that because I don't think I'll have a lot to offer in the way of advice but can offer support.
I think it's good that you want to take responsibility of your share of the R problems with your family. How did your mother react? I've been avoiding my mother for months while working through things because she does not approve of how I'm handling my R. Sigh. Sometimes family means well but aren't helpful because they just want your pain to end.
If you love somebody, set them free. http://tinyurl.com/2empx2g
