So my brother is getting Married, we have the same dad but different moms, and on his moms side he has two sisters also...so he's getting married in December and I'm pretty sure that his two sisters on his moms side are bridesmaids but I'm not even a part of his wedding in any way, is this okay? What do you think?

We're getting married in May. My FIL is telling us that he can't make it out due to health problems, which is what he always says whenever we invite him to come out. He has been very intent on walking my girl down the aisle, as she is his only child. I suggested that her uncle is able to come, she ask him to stand in, but she doesn't want to invite due to problems (said something about him being two-faced). We went out of town for the holiday weekend. Over the weekend, my girl went some friends to a dress shop nearby. The next day we went back and I got my tux there, too. The lady had recommended that she change the dress to a similar style for some reason. Now my girl is freaking out because she called again and the company no longer makes that style or the original style she picked out. She offered a new one and sent a pic but in a different color. My girl is freaking out about it! I told her to wait and the see the dress and try it on...she may actually like it better. And if she doesn't, we can change it. The wedding isn't until May, so there's time. She always gets a little frazzled this time of year, so with the wedding plans on top of her crazy job...and asking her to relquenish a little control is like going into combat with no armor or weaponry. It's not that she's Bridezilla. She's been dreaming of this day for a long time. I think it's more that her dad doesn't want to come than the dress. Even she said she needs to see it in white and try it on before making a decision. Her dad is pretty much the one who raised her, she never had a real relationship with her mother and found out last Christmas she passed away before Thanksgiving last year. So she's still dealing with that, although she says she's fine.
