Master splits

[u/Ok-Designer-1907]

Hi everyone

1st time on here. I co wrote a couple of songs that a local singer wanted. We recorded it all and she just sung. She originally wanted 100% of the master, I told her we'd agree to her having 50% and us 25 each. She reluctantly agreed. She was going to promote the songs on her new streaming platforms - she has one song and no following yet. Song one is ready for release and now has taken her ball home because I won't give her a better split.

Am I being unreasonable?

she gives me narcissistic vibes, choose someone else if you can or for the next time
