A good friend let her boyfriend's son, on-and-off girlfriend and their almost 2 toddler move in last fall to try to learn how to be a family. He got a job working 16 hours a week at a fast food restaurant and she took a job training course - neither working more than a few hours a day. Both my friends work, and when they would come home the first thing asked was "Can you watch the baby for a while, I (we) need a break!". His son spent most of his paycheck on illicit mood-altering substances, and the girlfriend most of her time on the couch sleeping. The would have big fights in the middle of the night, including him pushing her around and breaking things in the house.The baby momma finally moved back downstate (She hooked up with a new guy within days). My friend wanted the son out too, but her BF said he felt sorry for him and that he felt responsible for his problems (why he could not say). She finally told him that either the son left or both BF and son left, she did not care which, but by the end of the week the son was out regardless. Their relationship has still not recovered, but she is adamant that the son is never coming back into her house again.
