Gave up on rude cofounder

I walked away from a project I was working on in my spare time with a friend, after repeated attempts to introduce sound engineering were greeted with an angrily and aggressively uttered, "WHY?". An example: WHY do we need websockets to update an image instead of forcing the user to refresh the page manually? He is in dire financial straits--let him find an unpaid programmer who can appreciate being mistreated by a person who seems to think he's channeling Steve Jobs while his house is being foreclosed. I wad tired of waiting weeks and months before obviously bad and unworkable design decisions became evident to him, which usually involved a relative observing and pointing out the obvious.
