I think you just saved yourself from what could have eventually been a huge headache.

I'm assuming since you are applying for funding from YC that you are looking to start a company (YC acceptance or not). If that is the case, you should be glad that you weeded out someone weak while it is easy and not later on down the road. This could be a valuable lesson: Choose who you work with and trust very carefully!

If this guy can get up and jet on you this easily, think what would have happened after you actually started and financial and emotional stress enters the equation?

My advice is go find someone who you can really trust as a co-founder. Someone you know you can depend on when the going gets tough.
