So if you want to maintain a relationship with his family, you just have to know Not to discuss HIM...and answer their questions, IF they ask, truthfully but never in front of the kids.
I think you might be perfectly capable of not losing them.
Thanks 25! It is great to hear some real life stories to know that it is possible!! I have been really good about noting discussing the sitch with H's family. They have been in my life for so long that I hardly remember then not being involved. My H's sister has become the sister I never had. When we met, she was only 16. I went to her high school and college graduation, met all her boyfriends, etc. We were maid of honors in each others weddings, we are godmother to each others kids. I know that H's family will also love me, but I will fully admit that it will crush me if they welcome a new woman into their family if we get a D. But as you said, I dont have to worry about that right now.
