We've known each other for 12 years. About six years ago she moved like four hours away and while we don't see each other very often we do still talk over messenger. About 3 years ago she was in my bridal party and got bumped up to maid of honor due to an accident with my actual MOH. She really stepped up, was there the whole time and gave me the most beautiful speech and everything. 

Now her wedding is this October and I'm not in her party at all. I know she doesn't owe me anything, but I didn't even really hear about her wedding until we got the save the date cards. I haven't been able to to see her since my wedding and I've been busy with my new daughter and she works at a type of year round camp where she probably made better connections than she had with me. I don't know. I want to ask her why, but I don't want to feel petty.

Just to get a few things out there:

Like I said, I know I'm not owed a spot in her party just because she was in mine.

I'm not *not* going to her wedding. We were invited and I do care for her and I'd like to at least be there in some part.

I wouldn't be like "HOW DARE YOU NOT INCLUDE ME?!", More just a simple "Hey, so is everything ok between us?" Or something.

I don't expect to change her mind or anything.

I get that maybe life got in the way or that she just has closer friends than me. It still just kinda sucks a little.

So am I the asshole for wanting to politely ask my friend why she didn't include me in her wedding?
