Do many relationships fail because people fail to do their due diligence?

It one of the biggest factors that causes relationships to fail especially marriages is that people did not do their due diligence before coupling up? IMO too many people get lost in the lust or “honeymoon” phase of the relationship and rush to the “next level” too quick. They don’t take time to figure out what day-to-day life will be like with the person they choose. Many times when dating before living with someone you see their best or better foot forward. All the little small things like when is the trash really full? The dishes don’t need to be done until there is at least 7 pieces. Why put the dishes away when you will just be using them again anyhow, so just take them from the dishwasher. I don’t have to wash it I just jogged around the block and didn’t get it sweaty, I can get 2 more jogs out of it, etc, heap all that on top of the larger things like income and money, driving habits, communication and you have a recipe for disaster. When people buy a vehicle they do more inspecting than many do when getting or choosing a mate. Do people feel it is petty or in poor taste to get nit picky about the details when things look to get serious?
