I think in your case, the counting has pretty much stopped anyway. You are handling yourself with grace and poise and therefore as co-founder of the club, I grant you an exemption for a single reply.
If however, you invite him over and talk R talk for ages and still not get to a satisfactory conclusion, then the exemption will be revoked
Just do as you are and take your time. I mean how long has it taken him to talk like this?. An you're worried about rushing a reply?...no way girl. Take as long as you feel is right.
