Basically, we're all friends (me, 33f, her 42f and my partner 46m) and she came over where I spoke to her about a difficulty with one of my close friends (27f) and my partner. My partner was already aware of the situation but I did ask him about whether he was okay talking about it and he said yes. My friend (27f) doesn't like him and I was unsure whether to say she shouldn't come to our wedding and possibly even be friends. We spent some time talking about it, my partner joined in too and it all seemed okay. Until the following day my partner said he'd heard from our mutual friend that what he'd done was 'colossally' generous and he realised he wasn't okay with it. I understood his perspective, that up until that point he didn't realise but I'm kinda still annoyed with that friend for saying that. She didn't say anything to me, in fact sent a really lovely message to me about the evening. It might be that I'm overreacting - probably I am. My partner and I have resolved things now but I can't help but feel somewhat resentful still towards her. It feels like she stirred the pot. At the moment I'm left feeling like I don't want to talk to her about anything to do with our relationship again. A bit like she went behind my back. Am I overreacting? Should I mention this to her or is it on me to figure this out?
