LONG POST I just want to know, am I overreacting..?

Ladies, I'm sure I'm just overreacting but I want opinions.. My sister in law is planning my baby shower for next weekend and so far it's been nice having her do this for us, but when she was creating the event on Facebook to invite people she asked me "who do you want to go?" I told her to invite their family obviously and I would go in and invite my family and OUR friends. Well me and my boyfriend agreed not to invite one specific person my boyfriend used to be friends with along with his sister (we have had issues with him and she knows why we dont want him there.) Well when we told her we would like him not to be invited she said "Well I'll let him (my boyfriend) decided if he wants him to come or not. He will buy you presents if you invite him.) I told her we had already talked about it and he didnt want him to go either, and that him buying us stuff wont change our minds, so she waited a few days then invited him.. I saw that she invited him and decided not to make a big deal, so me and my boyfriend just agreed that if he goes we will just ignore our issues with him and have fun. Well I start going through the list again of people she has invited so far and I see that she has started inviting all of HER friends.. okay..? I talk to my boyfriend and he says he didnt know she was going to do that and was a little annoyed by it.. the friends she has invited of her own I have never met or ever heard of, same with her brother, he has never met or heard of them.. should I say something? Am I overreacting? I really dont want to make a big deal over it because I am really happy she decided to do this for us, but we don't even know these people. My boyfriend isnt sure what to say to her either 😕🤷‍♀️
