I would appreciate any advice on this. I re-married 5 years ago to a great guy. I have two grown sons living on their own and a 14 year old daughter living at home. My husband has 3 adult sons, the oldest, 25, living with us, one living on his own, and one living with his mother. I am having a problem with the oldest son who lives in our home acting as a parental figure to my teenage daughter. For one example, my daughter recently had a crush on a 19 year old co-worker. She and I had talked about it several times, and although in her wishful mind she would like to have this young man as a boyfriend, she knows it cannot happen. She also has had crushes on celebrities and many other boys. Anyhow, she gets to where she just talks and talks about whoever she has a crush/fantasy on to all of us. My thought about this particular young man she was crushing on was that he was nice to her, but wasn't making any advances on her as I was sure he knew about what age she was, and so far I have been correct about this. Anyhow, on to the step-son. The other evening my daughter and I were watching tv when the stepson came home. He kind of stomped into the kitchen with his fast food and then came out to where we were, looked at me with this arrogant stare, and declares that the guy my daughter is crushing on is on probation (which he was over a year ago for 2 months), and that he has this guys phone number and will call him if he needs to confront him...I suppose he had gotten someone (mom I think) to look into this guys facebook and find dirt on him. the SS says "I just thought you should know." Then he stomps off into the kitchen again. This is just one example. He has had someone look at my daughter's facebook before just so he could give her crap about an arguement she was in with another teen. He tries to offer her adult advice, but has no real concept of what it takes to be a parental figure. He tries to parent his own dad too as well as his younger brother. He tells my daughter how disgusting my house is, how irresponsible I am with her food choices, etc. My daughter is home schooled and he tries to tell me what he thinks would be best and where to go online to find this amazing schooling stuff. My stepson holds a part time job (maybe 15 hours a week). He only pays $100 a month in rent to have about 1/3 of our living space as his own. He pays his car insurance...and that is it. He stays up all night, sleeps all day, plays video games, reads constantly (which gives him his arrogant IQ), and sometimes all at once. He constantly is telling my daughter what she does wrong, like not picking up a towel in the bathroom. It is driving me crazy. I have told him about this before and we have had one major blow-up, which I do not like to have in my home. My husband seems afraid to lay down the law. For months I have been hearing how he has to talk with him about paying more rent and giving up some of his space so we have storage room, but it never happens. I know my ss is a good guy, but I feel a blow-up coming again. His actions tell me that he questions my abilities as a parent, as a wife, as a person. I believe he needs to grow up and get out so he knows what it is really like to deal with real life issues instead of trying to find issues here to fix. I have heard he cannot live with his own mom because of this 'holier than thou' attitude. Help
