LW1 Your parents most likely have your best interests at heart even if they are using a sledgehammer where a mallet would do. The new guy surfaced right after your breakup going through (coincidentally) his own breakup. How long did you know him before he is moving in? Was this his idea after a very short time? (1st sign of an abuser) You have a 3 year old son. Aside from the fact that you will not only be bringing the new beau into his life but _3 other adults_ in the form of this man's grown children + his grandchildren thus increasing the danger to your child, you are also increasing the instability in his life. New people, new ways, new things, is more than a 3 year old who was just separated from his daddy should have to take on.
