You didn’t invite people to your wedding
@m0therofdragons To be fair, she very much did invite them. She just did so verbally because her MiL said paper invites might make people feel pressured, when the wedding was abroad so more expensive to attend. They were very much invited- why wouldn't they have been?
OP says she gets on ok with them.
I agree with her that a card saying 'congratulations' and maybe a present would've been a nice gesture.
It sounds as if MiL was put out that you got married abroad without DH's brothers present.
@DelphiniumBlue As OP describes it, that was entirely the brothers' choice, they were invited.
IDK if OP goes into detail about MiL's comments.
"We are getting married abroad, no pressure to come" is not an invitation, quite the contrary
IDK. Maybe it'd depend how it was phrased/the tone. OP describes it as her MiL's idea not to give paper invites, anyway, not one she would've come up with herself without MiL suggesting it.
Explaining that your wishes to get married abroad trumped family considerations
Some people do get married abroad, it's not unheard of. It's their wedding at the end of the day. I think most people would just've thought 'ah ok, that's what they're doing for their wedding.' Maybe been a bit disappointed if they couldn't go, but accepted it.
