My two cents:

- The equity split is about incentivizing/rewarding you both for the work ahead, which is going to be much harder than anything thus far

- I would treat the 2 years as a sunk cost

- If you are true cofounders, 50/50 or 51/49 is the fair way to go

- Vesting diffuses the edge cases (either of you leave early, either of you turn out to be flakes), and is a necessity if you want to ever raise VC money

- It sounds like there is a question of him working only part time. In this case he should not get founder equity. Read the clerky docs as there can be severe drawbacks of granting significant amounts of equity post-founding
