So my step-brother married his wife about two years back, and yes he's my step-brother but I've always just called him my brother. He lived with his mom, not with us, but we've known each other since we were 5/6, and we've always gotten along great and been really close and I love him like my real brothers. I was extremely hurt when I wasn't included in their wedding, especially considering that my two real brothers were included. I was the only sibling left out, so I was the only one in all of the pictures that didn't match, and the whole thing was just incredibly uncomfortable for me, honestly.
Now I'm getting married, yay! And we weren't planning on including my step-brother and his wife, because I still feel so weird about it. It honestly sucks, I really wish that I could include my step-brother, but there's no way to ask him and not ask my SIL, but I absolutely don't want her standing up there. She's not rude to me or anything, it's just a sore spot with me, but everyone's acting like I'm the rude one for not including them.
I don't know what to do, I feel like crying.
