I don’t know just help
I’m confident in the fact that I want nothing to do with my fiancé’s sister. I have completely cut her out of my life for various reasons (traumas involving our children, racial issues, compulsive dishonesty, gossip about my miscarriages etc.). However, I am currently in the healing process, specifically in the acceptance phase right now.  I am trying to respect my fiancé’s point of view that at some point he does want our children to be in her life.
I accept that I had children with a person who is related to people who have caused me an extreme amount of trauma, and anxiety. This inevitably is going to cause some form of conflict or bump in our relationship which I personally want no part of. I don’t want us to fight. I don’t want us to be on different pages. I simply just want to live my life and heal!
He’s kind of in the middle, and understands both sides of the situation.
 I personally don’t believe I need to be playing tug-of-war with her in regards to our children. I’m certainly not going to play Tug-of-war with my fiancé when it comes to her either. I’m not gonna make him pick a side. I simply just want to be!.
 I can’t help but feel like I’m in this conflicting situation though because he doesn’t have a backbone with his sister. Now I have to live with the consequences or reality of having children with someone who always gives people the benefit of the doubt.
 I don’t know how long it’s gonna take me to heal from the wounds that she’s caused, but I would love to take my time and would not like my children involved with her while I’m in that healing process but I don’t know if that’s unrealistic and most peoples opinion?
