I've been split from eldest DC's dad since I was pregnant, remarried when DC1 was 18 months to a man he calls Papa. Now have a DC2.
Actually have a very good parenting relationship with ex partner although it's been tough as the relationship itself was abusive and he treated me terribly...that doesn't impact his parenting, he's been very good. He's been in a 3 year relationship and is now getting married - I'm happy for them, she seems nice albeit very young (early 20s). DC1 is happy for them although a little anxious about the implications...Think he's worried they'll have another baby now. Anyway, that's by the by.
Point is...I was v clear when we split that DC1 would retain his dad's surname. Because his Dad has always been his dad, we've never pretended otherwise & he would've been devastated to not be. DC1 has sometimes expressed confusion / upset that he doesn't have same name as me, Papa, his younger sibling....and don't even get me started on having to defend myself taking him on holiday. i hate having to 'prove' I'm his mother.
Now he soon to be stepmother will have the same name as him. Will never have that humiliation or feel that pain. Will have more of a connection in name to him than his own mother does. All because I tried to do the right thing.
AIBU to feel :(
I don't expect it to be any other way really. Just hate the whole surname situation. Perhaps I should have insisted on double-barrelling when he was born but I wasn't married then so his name would have changed multiple times. & with 2 very long surnames it'd sound ridiculous, poor kid.
