I had a really bad relationship with my step mother (not as bad though as some posted here) from ages 13 to 23. I am 31 now and in the past 5 years or so I have basically decided to not talk about those years and just let her and my dad be grandparents to my children. Nothing has ever been resolved about those years and I know that she won't/can't see/accept that she was terrible to me. I have never talked to anyone professionally about those years. They live far away from us so it is easy to maintain a superficial relationship and when we visit to make it mostly about the grandkids.
So the question is "Is this healthy?". I am the happiest person I know so this doesn't really effect me. And the reason it is coming up today is I read a journal that I had written 10 or so years ago reminding me of what happened and I am feeling a bit angry.
