I can't leave him because I don't want him alone with our toddler
I met him as he was divorcing his ex wife. She left him. He said at the time she complained he wasn't there for her. She was finishing medical school, they had challenging behavior issues with their (out of control spoiled) toddler, and she was having a complicated 2nd pregnancy. He chose that time to run for public office during a midterm election. A few months later she dumped him for the guy she was sleeping with at work.
