I am having a bit of an issue with my future sister in law and I'd really like to get opinions to see if I am overreacting to the situation(s!) Here is what we are dealing with: his youngest sister is 17 and like all 17 year olds, walks that fine line between maturity and extreme immaturity. She is extremely self absorbed and spoiled rotten yet the family turns a blind eye, except for my fiance who wont tolerate it for a second.
As we planned our guest list for the wedding, we decided that if you are under 21, you do not get a plus-one invite; we have to be budget conscious and also do not want to take on the liability of a possible underage guest getting drunk and injured. Little sister did not take kindly to this and refused to speak to us until we caved and said she could bring her HS boyfriend (I'm still not happy about it). Now, after she 'won' that, last night she became visibly upset over our guest list because her OTHER sister's best friend is not invited. This girl in question is not our friend, not a family member and certainly not someone we would consider inviting. At a formal dinner last night, little sister threw a complete fit about this; crying, sulking (in public!) etc. because SHE considers this girl like family and now of course, will not speak to us AGAIN.
Neither of us are planning to give in on this; we have no attachments to this other friend and frankly, no desire for her to attend. His family is a bit put off that we have 'upset S******* for such a silly reason'. As I said, she is coddled still at 17 and very used to getting her way through guilting those involved...
Are we being unreasonable? I am still a bit prickly over the '17 year old gets a plus one but my cousin who is like a brother to me and is 20, does not' so i fear i am overreacting. Your opinions are very much appreciated! Thanks to you all!
