So yesterday I was told I was meeting a couple of people for breakfast and when I did it turned out to be a surprise shower. If you see one of my other posts I did know it was going to be a shower (my FI spilled the secret) but all I really knew was where it was and what time to be there. I was really surprised at how many people showed up because I thought it'd just be like 5 family members showing up for brunch and it ended up being more like 12. One of the people in attendance was my aunt who is not invited to the wedding. I have another old post about why she's not, long story short she's married to my uncle who has been awful and hurt my grandma and is just a bad person. I know that people not invited to the wedding are not supposed to be invited to pre-wedding events so now I'm wondering what to do. She did give me a gift and I'm wondering do I have to invite her now? Do I send her the gift back and say I'm sorry there was a misunderstanding and I appreciate the thought but I can't accept it? Do I just write a thank you note and still not invite her?
