The truth is that every founder is different and every one of them has issues. The successful team is going to be able to compensate for each other's weaknesses.
The key here is to really step up the communication-- if you do that and still nothing works out, I'd say only then start the plan to leave.
The day you believe in your heart of hearts that you did your best, but it wasn't enough to compensate, then you've fulfilled your obligation to the partner. I don't sense the OP has yet tried his true best-- or else he'd know there isn't more he could do to make it work.
Would you want him to bail/cut-out on you because he felt like you two couldn't communicate? At least without coming to you first to figure out a way to improve the communication issues?
