We should live together to test compatibility but analyze: what does cohabitation actually test? Map cohabitation: reveals daily habits, financial compatibility, domestic partnership. Calculate: what living together reveals vs. what it doesn't vs. commitment level. Show me the cohabitation reality: tests compatibility but not commitment. Give me the truth: this will reveal these things, won't reveal these things. Include: whether living together is right move, what it actually tests, and if we're using it to avoid marriage conversation.
