1. just moved into offices, now you have a burn rate and clock is ticking, increasing pressure. maybe should have stayed working at home/Starbucks
2. have an intern and one who needs guidance. why this early? the more people you have the more complex things get, and in the case of your tech co-founder sounds like a greater burden on him. he may not like coming in now when the intern is there because the intern will interrupt him and so he'd prefer to work at home or at later times of the day
3. he's your 50% co-founder and main tech guy, NOT your employee. if I were in that situation, I'd consider myself as not really having a boss. at best, a partner. it's true he needs to deliver and you need to have a mutually trusting relationship or it's going to fail. there are many downsides to a startup but one upside is the ability to have no bullshit, no bureaucracy, no boss, and work whenever and wherever and however you want, as long as the work gets done and you move ahead at a sufficient rate. If you really and truly think he's not pulling his own weight then the earlier you can part ways with him the better. None of us here can truly know enough details about your situation to say for sure whether this situation is your fault or his fault, but if the trust is gone it may be best to bail.
