My boyfriend elected himself to do some work under my kitchen sink to fix a problem with my dishwasher not draining, in which he also is responsible for. He rigged the pipes together yet claims he did it correctly. I live in a condo above people, and my neighbors below me are now threatening to sue me for water damage from the leak that ensued. Would you be pissed at him if you were me? I’m ready to scream because this is the third time this has happened now. His intentions were good, but he claimed to know things he really didn’t know. He also has never owned a home and doesn’t understand how liability works, despite my communication. How should I treat this situation? I don’t want to overreact and lose my cool.
