Okay so this is a little complicated to explain however I’m in need of some help. So my mums best friend who I’ve seen as an aunty my entire life, is getting married next week & I am so insanely happy for them. At the start my Father wasn’t invited & he was slightly butt hurt about it but understands that weddings are expensive & hadn’t brought up his feelings to Mum or anyone else for that matter. We had hosted the bridal shower at our house, which he helped with the set up & was ultimately kicked out when it started. My aunty has a friend that at first I thought was quite funny & kind, until she started making comments that I feel we’re not appropriate. She leans in to my Mums ear in-front of my Dad and says “when you wake up and leave him I’ll be here” obviously my Dad was gobsmacked and acted like he wasn’t too bothered in the moment but it’s stuck in his head now (we’ll call this lady Patricia). My aunty also made a comment saying that “he’s finally growing on me” after decades of supposed friendship. Now at this point my Dad is floored & questioning what he had done to deserve this kind of disrespect in his own home & I end up going to my room and not wanting to engage with anyone because of the blatant lack of respect. At the end of the bridal shower my dad is given an invite to the wedding, shocker, he accepts & offers to try & organise late minute cars for them as the previous ones fell out. In the meantime my Mum is playing maid of honour and being with her best friend every second of the day which is understandable however she’s being going over to Patricia’s house at questionable hours for long periods of time and is slowly starting to distance herself and shut down, do I think she’s cheating absolutely not however something is deteriorating in my parents relationship. Just a few days ago my dad received a message that he is no longer invited to the wedding because he isn’t in with the ‘click’. Now, I am very protective of my parents & family so if one of them is disrespected or thrown aside I care no more about that person’s opinions and ultimately either never talk to them again or tolerate them from a distance. I’ve seen my dad try & spend more time with mum, taking days off work, making plans for dinner & engaging in general conversation & to put it simply it’s like talking to a brick wall. I understand it’s not my place to play relationship therapist however I’m more concerned about the forthcoming argument with mum when I voice that I no longer respect her best friend & don’t want to be involved in her wedding, which will end in “you’ve always loved your dad more than me” so on & so forth. I need her to understand that if the same thing was done to her I would do the exact same thing, I try to treat my parents equally but i’m unsure how to handle this situation without causing more harm. Any help is greatly appreciated 🙏🏼
