I think I have a problem

Just had a massive row with partner about his daughter (who unfortunately was in ear shot of the whole thing)!

He took her (13) and my daughter (16) out to arcade. We have his daughter half of all school holidays.

Anyway she decided to put her brand new phone on a random table when out and it got stolen! Keep in mind I haven’t finished paying off for that phone yet. (I paid majority) (she also only ended up getting this phone cos she rings her dad (my partner) crying that her old phone (which he also brought) is rubbish my friends all have better phones. He gave me £200 so that I could order her a brand new latest model phone from my catalogue.

Anyway so after it got stolen he don’t ring me he rings her mum (haven’t a clue what for or why but anyhow she explains that old phone is still in her room so don’t buy her a new one etc

He then rushes out and buys her a new phone again (a refurbished latest phone for £300!!)

No discussion with me not a word. He gives her the phone (4th phone in 4years) and she has the cheek to say where we going next I’m bored!!

So I pull him up on how he never had a discussion with me and that I hadn’t finished paying for the last one and she lost it she should learn etc and I was told “I’m not having my child walking around with her old crappy phone so why do I need a discussion with you for you to say no ” I lost my shit - also because my daughter lost her AirPod charging case and he promised to buy her a new one but still hasn’t and says it’s cos she was rude! He daughter can also be rude (I usually get ignored by her if I say morning) He then had the cheek to say “why you acting like this you have a problem with my kid you do it every time she comes down” like wow. Everytime she comes down he’s usually at work so it ends up on me to entertain and take the girls out. I make sure I have pictures of her in our home etc

Please tell me I’m not wrong for pulling him up on this?
