My DH’s close friend got married a few years ago, they’d been good friends for about 10 years.
I had met him and his fiancé plenty today times, we’d all socialised together, we’d been to each other’s Hen Nights, they attended our wedding etc.
When they got married the invites said no babies over 6 months old allowed but younger babies were. This included bottle fed babies so it was not about about young babies who were reliant on their mothers for feeds.
At the time of the wedding our baby was two weeks over the 6 month mark and was exclusively breast fed. My DH spoke to his friend and explained that I wouldn’t be able to attend unless the baby could come and as the baby was only two weeks over the ‘cut off point’ would it be ok. The Groom had no problem with this, said of course it was fine and that he’d let his fiancée know.
A few days later the Groom got back in touch and said that he’d tried his best but his fiancé didn’t want me coming because although our son was 2 weeks over the rule and EBF she didn’t think that was a good enough reason.
Her view was fine, it was her wedding, they can invite who they want to etc etc but the problem my DH has with it all was the fact that even though the Groom had no problem with me attending the wedding, because his fiancé had said no that was the decision made, despite my DH and the Groom having been close friends for over 10 years.
His friend was really apologetic, much like your cousin, said he really wished he could have talked the bride round but he hadn’t been able to.
My DH’s view (as others have pointed out on here) was that it wasn’t just her wedding, it was his friend’s wedding too, and he was upset that his friend hadn’t stood up to her and said that he wanted me and the baby to come because he should have had as much ‘say’ regarding the invites and guest list as she did.
As apologetic as his friend was things became very strained and my DH declined the invite to the wedding.
We have seen the couple many times since then but things have never been the same.
The point I’m making is that people can invite who they want, they can have ‘rules’ about who can and can’t come BUT your cousin should be standing up to his fiancée because sometimes friendships and family relations are more important.
If your cousin isn’t prepared to invite your partner then you should decline the invite because it’s very disrespectful to your relationship and it actually proves how little your cousin wants you there if he isn’t prepared to stand up to his fiancé.
