Op, your feelings are your own, but honestly,
I think you are being a tad harsh.
What young men in their twenties are very devoted to their families in general and their sisters in particular?
And loads of people didn’t see or speak to family as much during the pandemic and are only catching up in the last year or so.
I have a nephew that age and I know I am an aunt rather than a sibling, but I would be a bit worried if I heard from him constantly! The odd WhatsApp is fine!
I get that it’s hurtful when your messages don’t receive a response but your twenties are the time when you are out and about and being a bit selfish; focusing on friends, travel, establishing a career and finding a partner.
He’s your brother! Go and celebrate his wedding and don’t make it all about you and your grudging feelings. Fine if it turns out that you are not close and you don’t like his future wife, but give them a chance at the start fhs!
If her family live nearby then they are obviously going to spend more time with them. You sound a tad jealous or resentful about your brother establishing his own life. And I understand that is an adjustment as a sister. Or is this attitude coming from your parents?
Try and dig down in your own mind as to where these feelings are coming from, and what exactly has he done wrong?
To my mind, the job of family, is to rally round and support young couples as they start out in life. Irrespective of personalities and little niggles. See the bigger picture! I’m
sure that your brother will really appreciate your support on his big day.
As soon as he and his new wife have dc, their focus will inevitably turn to family and your relationship might evolve.
I think the minimum for a sibling’s wedding present would be £200 and I hope your sil to be is not on Mumsnet as you have been very specific about details. Good luck.
