<human>: We've been together for 2 years this past Oct. We own a photography business together and working on this charity calendar project. I have done everything except shoot and edit the actual photos. 
Well I bought the wrong size posters to ship out and spent a lil over what we planned. He freaked out and starting arguing and then went onto our business page (on Facebook) and makes a post saying my ex-business partner ran off with the shipping addresses. Like seriously so unprofessional and not true since they were all in the email he has access to. 
Now that we're arguing about all that because there was no money made on the posters, our actual relationship is... well I don't really know where it's at since we aren't talking at the moment.  I love him (even though he's being an ass) and of course do not want to break up and not have him in my life but this business stuff is horrible. We do not agree on the way he wants to run it and I've tried just stepping away and not being his partner but then nothing goes right and I'm sucked back into running it all. 

Has anyone been in a business relationship with their significant other? Did it work and how? I'm completely at a loss.

<bot>: I'm in a business relationship with my boyfriend and having a hard time keeping them separate and can't seem to just stop being his business partner.
