Choosing the perfect moniker for your baby can be really tough - some people may wait until they see their bundle of joy before making their minds up, but others may be completely set on a name. One woman took to Reddit's 'Am I the a**hole' forum to explain that she and her ex-husband share a daughter, who has a Frozen-themed name as she's a 'huge fan of the movie'.
She was, therefore, heartbroken to learn that her ex, who got married less than six months ago to a new woman, was now expecting a baby - and they'd planned a very similar name to the one her daughter already had.
She wrote: "My (31F) ex-husband (35M) got married less than six months ago to his girlfriend (25F) and she got pregnant very fast, recently he told me that they were having a girl.
"I am a huge fan of the movie Frozen, so when our daughter (6F) was born I wanted to name her Elsa and my husband agreed to that. I know it is a little dumb to name your kids after things like that but it is not a super unusual or ugly name, it is pretty and it means a lot to me. My husband and I divorced when our daughter was three, we don't hate each other but we are not best friends either.
"The issue with the new baby is that he explained to me that after he told his new wife the story behind the name of Elsa, she proposed that their daughter should be named Anna, so they could be sisters like in the movie. For me, it is totally unfair that they are stealing my naming process from me like that. What if I have another daughter?
"It would have been perfect to name her Anna and now I wouldn't be able to do it without it looking like I am stealing from them. My husband doesn't even like Frozen that much. He always said his favorite Disney animated movie was Bolt. I don't know if the mother likes Frozen but I am totally sure she doesn't like it as much as me.
"I demanded to him that they choose another name but he thinks I am acting crazy. I called my divorce lawyer but she doesn't think there is anything we can do about this. My mother just laughed at me. I feel so defeated. My sadness turned into anger and, in an impulse of rage, I called my ex-husband.
"I told him that if they insisted on using that name, I would make everything I could to sabotage the relationship between our daughter and theirs, so they never were real sisters like Elsa and Anna. He got really angry and said horrible things to me.
"I immediately regretted saying what I said and it is not true, I would never do that, but this whole situation has been so horrible for me and now he is really angry too. I think that I am ultimately in the right about why they shouldn't use that name but I was wrong in saying what I said. I want to insist on them picking another name but without going too far. Am I the a**hole?"
In the comments, people were shocked that the woman had been so demanding, and she received a lot of backlash.
One wrote: "Take a cue from your favorite movie and let it go."
Another said: "She called a lawyer? Over the name Anna? Girl needs a life."
"Her own mum laughed about it", a Redditor jibed.
Someone else said they couldn't believe that the mum would take it out on the half-sisters, writing: "The part that killed me was her taking her Disney frustrations out on two completely innocent toddlers.
"Totally a normal and not-unhinged-at-all way for a grown woman to act about a cartoon. Also weird that she'd use the word 'real sisters' for two cartoon characters but not two actual real-life half-sisters."
