I have two friends I've had for ten plus years.
I introduced friend A to friend B about three years ago.
Friend B starting dating friend As brother quickly after.
Friend B is now married to friend A's brother making them sisters in law, they live very close to each other, have the same gender/aged kids who are best friends, both having more babies (my kids are older and I can't have more). They see and talk to each other pretty much daily. I've gone from being close with both individually to seeing them once every month ish, one is better at messaging than the other who rarely messages, she just isn't great with her phone.
I love them both to bits and I'm happy they have each other, but the selfish part of me hurts as I see myself get left out more and more, through no fault of their own. They're family now so it isn't their fault, and I'm a 35 minute drive away. I do try to put the effort in but it can feel one sided sometimes.
Am I completely a cow for having these negative feelings?
