I personally made my invitation list for my baby shower. However, I didnt't send one to my sister in law (she's married to my husbands brother) for a good reason I believe. We haven't always had the best relationship and since I've gotten pregnant the relationship has only worsened.(ex. Not saying hi when she sees me and completely ignoring me) I wanted my baby shower to be comfortable for myself hence the reason I didn't invite her. But my MIL caught wind that I didn't invite her and made a big deal because she is 'family'. Was I in the wrong to not invite her?
