Your problem is one of team building. There's you (non-technical) and a "co-founder" (some technical) who aren't really communicating with each other. We've got your side of the story but not the other's. Then there's the lack of a good CTO/technical lead. I know Y-combinator likes to have teams live and work together and that is for a very good rason: it builds the team into a unifying force!

What do you have to do? 1) Build your relationship, first. Go on a retreat together. Get a cabin somewhere, go hiking, escape life, talk, grow, code, design, build, mock, fish, cook, eat, sleep. Do not network, call, email, read news, or communicate with the outside world. Focus on yourselves and your project. Build off that energy and take it to the next level. 2) Either that succeeds or you fall apart. Lesson learned. Move on.
