Gosh, it really hurts when you are there for someone else and they're not there for you doesn't it? Ouch, I feel for you; it would take everything in me not to just smack her if I were you lol.

When I was wedding-planning, I feel like I really didn't get much help. When my SIL got engaged, I really jumped in. They didn't do a rehearsal or anything and there was no wedding party. So when the big day came she didn't know how to go down the aisle, what to do for the "giving of the bride" no one to hold her bouquet or fix her train. I did all of that for her and went to the hair salon with her and everything. Not only that, but I was her florist. At my wedding, she and her mom went to a totally different salon than me, my mom, and the other bridesmaids and that really, really hurt my feelings. I'm over it now, I love my "sister" (we don't even use the term in-law). What bothers me now is that everything her family, her mom, dad, the cousins talk about is her wedding, her dress, how wonderful this and that was blah blah...and I never hear anything about how nice mine was or how memorable something at my wedding was and it bothers me.

I pick and choose my battles, so honestly, I would either confront her and risk making her mad or get over it and ignore her and find someone else to be the MOH or at least do the MOH duties for you.
