AIO for my girlfriend wanting to breakup with me

CONTEXT:

3 days ago my girlfriend and I showered together, she intentionally kept turning the water on cold to mess with me, I told her to stop , put cold water on back to try and phase her, I put the water on hot not thinking much of it however she said she got a burn, she used to stand under hot water as a kid and I triggered her AND she also stayed under the hot water after I left the shower as self harm.

That was 3 days ago after saying she needed space. We’ve been texting off and on during this time but she texted me this today.

This isn’t really an AIO bc her feelings are valid but I could just use some feedback, tips on the situation Context we’ve been dating for 3 months. And this is our second argument , check my page to see what the other argument was about
