I agree that being honest is the most important thing to do at this point. Beyond that, I think that the first question you need to ask yourself is : "what do I want, long term". Obviously we don't know what your project is about, but do you need a non technical co-founder? If your project is a Dropbox (pure tech product) or even an Instagram (social network), I am not sure. If it is a SaaS or marketplace type business, then maybe. And I say that as a business/product co-founder myself. In general, I would recommend being able to answer these questions: onstartups.com/tabid/3339/bid/99/Important-Questions-Startup-Co-Founders-Should-Ask-Each-Other.aspx If you cannot, talk about it with your co-founder, and if you can't find satisfactory answers, consider splitting.
