If your current or ex partner was/is a lazy bastard - can you no look back at your early days together and see the signs?
For example my ex would -
- let the dishes pile up (unrinsed) for days
- shower only when necessary never brushed teeth (ever)
- leave clothes shopping to older female relatives (they would also dispose of any that were tattered or didn't fit anymore)
- had no hobbies or interests outside of gaming/ watching films or tv
- didn't read books (would just skim reviews)
Mind if anyone were coming round suddenly it as all systems go to clean etc and be seen. Glad that's behind me 
What could you now see were warning signs? How did/do you cope?
