Background:
My brother got married to his wife last year (after only knowing her for a few months). They had a very rural wedding where they didn't invite many people. Therefore most of my parents friends have never met my brother's wife.
My mom and her two best friends (who all have daughters around my age) started a tradition when the first daughter of the group got married years ago for a shower. Every time there's a wedding, baby, etc of the daughters of my mom and her friends, we get together at a restaurant and have an intimate shower with our group. We've had this tradition with the same people for almost 10 years now. I've grown up with my mom's friends and their kids.
I'm getting married and it's my turn for the shower that we do with this group of gals.
I don't really want to invite my SIL for a few reasons: 1- I hardly know her. I've only really met her two times, a family christmas and their wedding. 2 - she's pregnant now and with our group of people (that we have this tradition with) haven't met her and I'm being a brat and don't want her to come because she'll take the attention away from me and my day. My bro has always overshadowed me and for once, it should be about me and my day and I don't want to invite someone into our "group" at this function.
Am I being too oversensitive by not wanting her at this shower (there will be many more she can come to). I just don't think this is the right venue to introduce her to our group.
Thoughts?!?!?!?!
