Two years ago, he and I broke up after he was abusive toward me, and at one point I sent a message to our shared friend group explaining the situation and why I wouldn't be around anymore. (We're all late 20s.) Now, he's gone through therapy/anger management and we're giving it another shot. 

His female best friend and I haven't really spoken since then - she took issue with me telling the group about the abuse and didn't seem to believe me. When my boyfriend recently let her know we're getting back together, she claimed that I had told her back then that he'd raped me. 

This NEVER happened. In my two-year-old message I was very clear that the abuse was emotional with one instance of physical. Sexual abuse was NEVER a part of it and as someone who takes sexual assault very seriously, I would never make something like that up. This girl claims she deleted the messages where I supposedly said this but it "stuck in her mind."

Partner told me "she'll apologize eventually" and expects me to "make nice" (his words) with her when she does, because he wants us to get along. He doesn't seem to understand what a serious accusation that is and how much it hurts me. I am not interested in being around this girl and would not be comfortable spending time with her. I also feel somewhat betrayed that he doesn't seem to be angry with her at all, not on my behalf OR his (this is someone whose hair-trigger temper has been an issue in the past.) If the situations were reversed, I'd cut out that friend. We had an argument about it and now he's upset with me for "bashing" him and refusing to get over it "because I love him."

I genuinely don't know if I'm being unreasonable or not.
