So this past summer my FI got invited to his cousin's wedding. It was apparent that he was B-listed, he received the invitation about a week before the wedding. He really wanted to go though and catch up with these relatives but the invite was only for him. He called his cousin and said he wanted to come but he wanted to bring me, his fiancee. Apparently they had no idea I even existed! His cousin apologized profusely and asked us both to come.
Surprise surprise I got sick the day before the wedding so I couldn't go but I encouraged FI to attend and hang out with his family. He went and had a really good time. When he was congratulating his cousin and the bride they called me on his cell phone to say they hoped I would feel better soon.
I thought that was very sweet of them and let FI know that we should invite them to the wedding because I would love to have them there. One thing slipped my mind though as my FI left for the wedding that day. We had purchased a card previously that my FI just threw some cash in it before leaving it on the gift table. It wasn't this weekend that I asked him how much money he put in the envelope. "$10, everything I had in my wallet."
My first instinct is to find something on their registry and send it to them. I just don't think $10 is substantial for a wedding gift, at least for what I would rather spend.
So at the end of this long wall of text I have a few questions. Despite being B-listed should we send another gift to the couple? And if we do what should we say in the card? I probably wouldn't stress about this as much if they weren't future relatives.
