Names changed to protect identities.
My best friend Sabrina who I’ve known for 16 years now, has been with her girlfriend Allison for 9 years now, they’ve lived together since 2014. (yes she is bi)
I’ve been with my girlfriend Kate for 13 years now, she moved from Thailand to be with me. We were planning to move to Thailand but the pandemic hit and we can’t do that yet. But we want to. We’re wealthy enough to, got no kids.
They’re a self-described “very femme less couple” and hate it if people assume one’s the masculine one, one’s the feminine partner.
I’ve known Sabrina since September 2004. Recently via my cousin Alex (works as food delivery rider) found out that Dad had been cheating on Mom with Sabrina, she said she’d seen Dad kissing this woman in a McDonald’s car park with her sitting on the hood of a sports car. She did get a photo which she sent me.
She didn’t confront my Dad but was embarrassed; she’d seen that as it was on her regular delivery route.
I’m an only child with no siblings. Dad was very upset when Mom was told she could have no more kids; my own birth was difficult according to mom.
I told her over Whatsapp that it was my best friend’s girlfriend and she was shocked. We didn’t get a chance to meet up in person so talked over Whatsapp instead.
As it is, I’ve told Sabrina, showed her the photo and she was crying; saying she wondered if she’d regretted 9 years of being with her and wonders what a postpandemic dating market will be like for her since she’s nearly 40.
I also confronted my Dad about it, and he didn’t deny it, saying “Mom’s getting obese” and “She’s losing her drive to Netflix”.
But those two things are nonsense; Mom’s 61, does hiking. She’s always been fit.
Dad seems to want to leave Mom for Allison and they seem to want to be married?
Allison as my stepmom? Weird or sick??
Looking for advice on how to support mom and my best friend.
