I'm on month 8 w/ my co-founder (okay, that's a lie, we've been friends for about 5 years or so), but that "honeymoon" period wears off quick and little things start to creep up. Communication is key, and so is unity in vision. If you ever have any doubts, then bring it up, even if you brought it up yesterday. This is something that can't be beat to death, and will save you from doing stupid stuff like building things then being like "why did you build that, the customer wanted X" or "i thought we going to focus on Y". I know you're venting right now so sorry for the long diatribe. Kind of sounds like you're past that point of reconcile. Bummer. Hope things work out.
