Like others have said, one option is to have a chat with her.

Another option could be coming up with a percentage that fits your 30% increase in earnings:

Assuming you start with a 50/50 split, we can add a 30% increase to your share:

0.5 * (1 + 0.3) = 0.65

This 30% increase leads to a 65/35 ratio, where you would be paying 65%, and she 35%.

Let us know if that fixes the issue. I’m having the same problem on my end.
