Raising a teenager between two households is rarely simple.

So when her daughter got the long-awaited green light for ear piercings from her ex, only to watch him backpedal and try to make her the bad guy, she refused to play along with his little game.

Read on for the full story.

AITA for siding with our daughter and telling my ex he has to make good on his promise?

I, 36F, co-parent Mila, 15F, with my ex Leo, 34M.

We are civil around Mila, and only communicate via text.

But occasionally, they disagree when it comes to allowing Mila permission to do certain things.

Since she was about 11, she has wanted to pierce her ears like a few of her friends have.

My mom got my ears pierced when I was a toddler, so I was all for it, but Leo said no, and she had to be a bit older.

But after some convincing, Mila finally got her dad to agree.

Over Christmas, Mila was at Leo’s, where she got him to promise that if she still wanted to pierce her ears after her birthday, he would take her to get her ears pierced.

When he dropped off Mila, she excitedly told me that her dad had finally agreed.

Little did she know, Leo had no intention of keeping this promise.

I think Leo was banking on Mila forgetting he had agreed, because she asked him to book the appointment for next weekend after her birthday, but she also wanted a helix piercing, and he called me to say he wanted me to say no.

I told her that it was not fair of him to throw me under the bus or to back out, as he had promised her she could, and that I had agreed years ago she could, and it was now his problem to talk to her about it.

So she let Mila go through with the piercing, regardless of what Leo thought.

Mila told me she had planned to go after school this week while she was with me, and I didn’t tell Leo.

Leo saw Mila’s new piercings and blew up my phone that I didn’t stop her or tell him.

And I replied that it was important for him to show her that he would follow up on promises.

Our custody agreement allows her to get piercings, and it is legal where we are for her to get them at 15.

But then someone else started weaseling into their business.

My sister said I was only harming my relationship with Leo, and this would just cause more problems later down the line.

AITA?

Leo basically just wanted her to say no so he wouldn’t have to. Not cool, man.

What did Reddit have to say?

This commenter thinks this situation is far too strange a hill for her ex to die on.

Sometimes dads’ “opinions” can start to feel more like ownership.

This user has three things to say.

It’s only earrings at the end of the day.

She simply stepped aside and let him deal with the consequences of his own promise.
