I think something like this should be divulged from the start. If it's not something a person can get on board with, why waste everybody's time?

Ugh. Ok not to say something on the first date, but once you decide to go past that point, you really need to be upfront about things like this.

My real estate agent lives in the same house as his ex and the kids. They turned the basement into a suite and switched weeks so the kids had stability. Great if you can do that, but murder on your ability to develop a future relationship.

Not if he was the last man alive.
