Your best bet is to get a divorce now. That way she has time to find someone else to help raise your kids, since you won’t really have the time or energy.
Alternatively, find a cushy corporate job with low expectations that is completely outside the domain of the company you want to build. Then, bring your personal laptop to work and work on your side project. Make sure your contract doesn’t give them rights to your outside projects. Make sure you use a separate network (e.g get a 5G hotspot). You might want to fake your commit times so it all looks like it happens during non business hours in case you are sued and audited.
