So let's start off by saying I believe in mental health and psychologists and if you need help get it, all names are made up, but just to simplify.  


My partner(Ben) suffered years of abuse and developed psychological issues that I don't really want to go into here, that isn't what this post is about. Ben has had a divide in his family since his abuser went to jail. For a while there was no contact between my partner and his sister(Jess). As Ben's partner I have head all sorts of stories and horrors that come from systemic abuse and the grooming of Jess. Since then both Ben and Jess have had therapy and Jess has since had 2 kids  


We met up with Jess and her partner, it went okay, but then this week. Ben was told the only way that he could see Jess's kids, was if Ben got a Psych evaluation from Jess's partner, next year after he finishes his qualifications.  


I am adamantly against this, believing it is a major conflict of interest having Jess's partner do it. I suggested instead that he came to a therapy session or something different, trying to find a middle ground. I don't think I am an  asshole I think it's a complex situation.  


TL:DR: Sister want's my partner to get a Psych evaluation from her partner, I think that is a conflict of interest.
