You made a huge mistake by moving your children into a boyfriend’s house when you’ve only dated him for 5 months, during which time he broke up with you to get back with his ex “for closure”. 😕 Dating as a single parent is a LOT different than dating as a person with no children. You come second to the children. It’s not fair for you to drag the kids through this kind of situation, so fix it and do damage control. Move out of his house and focus on the kids (they’ll probably have some adjustment issues) transitioning. Then, consider finding someone to date who has “matching luggage” in the social and economic departments — in other words, a guy who’s also a single parent who understands better what it’s like to date and marry a single mother with three kids.
