UGC unlimited usage pricing question

Hi, hoping to get some feedback from the UGC community on this contact: brand wants unlimited usage and I’m pushing back on that. This is their response to me saying they’d need to pay for usage beyond 60 days:

“Unfortunately, renewing paid usage rights every 60 days isn’t how we structure our UGC partnerships.
That said, we’ve really enjoyed working with you and would love to continue. We’d be open to paying a higher rate upfront instead of renewing usage rights every 60 days.
If you’re open to that, let us know what you have in mind. Hopefully we can find something that works for both sides.”

I have no one to talk to about this, whether they had experience with a situation like this and how they responded. Would love to know your experience, whether this is worth it or not? They have been a good brand to work with but this is the third time and the unlimited usage doesn’t sound right to me anymore( I started working with them when I was stating of my UGC journey, don’t judge lol)
