I suggest considering an nth option: split the baby.
Can your startup be split into two business lines? One that focuses on enterprise, one on consumer? Commit to noncompetition for say, 3 years. Everybody happy because they're apart.
Finally, an n+1'th option: seal up the business as an IP enterprise, licensing what you've already built to both founders' new ventures. Evenly split the licensing fees. Agree on a licensing structure open to both founders, where it only eats up about 10% of the expected margin, and realize that 5% is pretty much going right back to where it started. Throw on a shotgun clause.
The odds say at least one of your new ventures will fail- this will allow survival of the fittest from an otherwise nasty divorce.
One of you two decides what equity the one receives who leaves the company, after that the other one decides whether he wants to take the equity and leave or stay.

I would advice you hire a lawyer to negotiate on your behalf. His/her brief would be to aim for a 50/50 split of assets or 25% equity shareholding as compensation for leaving the company(although your initial ask would of course be higher). You could also ask for outright cash
(These numbers could be different if your founders agreements dictate something else or your contributions to building the company are unequal)
If that would make your life better/happier -- it might be an area to seriously explore. What would 'something else' look like to you?
