Groomsman [my brother] backed out of wedding

I don't think you're overreacting at all, I can't believe your brother refuses to stand next to you all because of YOUR decision for YOUR last name. Guess that does show you where your relationship stands, I'm sorry he's being so selfish about this. What you and your FW choose to have as your married name is no ones business but the two of you. But at least you'll have your son as your best man, that has to be more special than anything

I definitely don't think you're overreacting. We are changing our names to something that does not carry on my FW's maiden name and luckily her sisters haven't argued at all. What we choose for our name is important to us but does not affect anyone else. I'm sorry that your brother can't see that.

Not at all. I think what you are doing is kinda sweet actually. He is the one with the issue, not you.

Definitely stick with your original plan. I'm sorry that your brother is reacting that way. IMO he sounds incredibly sexist. Women change their name all the time and no one bats an eye. I decided to change my last name to my H, but that was my choice. No one in my family thought it was because I was ashamed of my last name or had any problems with it. It shouldn't just be expected that a woman will change her name and I applaud all men who don't feel the need to maintain these type of traditional gender roles. Try to not let your brother get you down, be confident in your decisions and enjoy marrying the love of your life!

You're definitely not overreacting. He has a reason to be attached to the last name, you do not and want to make a new path with your new spouse! The privileges he got with your father's last name definitely clouded his judgement.

He's being dramatic - even if he does disagree with you, he can still stand there and support you, like a brother should. Don't compromise on what you want just because he doesn't like it. If he's going to let that drive a wedge between you, then you don't need him next to you at all.

I love the blended name; we're looking at doing something similar!

Definitely not overreacting. For starter's, your relationship shouldn't hang in the balance of your name! Second, it's such a personal and special choice, but also life-long. You're not compromising on something little like menu options, this is a huge decision that you should be solely in charge of.

And third... When I read your formula I thought "Aw! How sweet! I should do that!" But it occurred to me my last name would be Louse if I did
