I had a discussion with my husband earlier this week about the way I would guess I am most annoying to live with. I try and analyze and logic everything. Best way to load the dishwasher? I have a researched system. Buying a new house? I had a spreadsheet with multiple criteria and a weighted metric for each. I research everything, and try to apply logic to every situation. I took one of those online psych assessments recently regarding personality type, and it said I don't need or seek out romance because it isn't logical enough for me. This is a huge pain in the butt when he just want to know what to do for lunch. What are your cohabitation issues?
