How to get rid of unwanted "guest" discreetly?

Firstly, your brother, despite paying his and her way, has no say in whether this girl can move into your house, except as a single family member. Secondly, it seems to me that she is very inconsiderate of anybody other than herself. So, having considered this, here's what I would do, if I were your Mum or Dad, and the owner of the house. First, I would call a family meeting of all those contributing towards the upkeep of the home, and the food... in other words, exclude her, or call the meeting for when she was not at home. At this meeting, I would encourage all to give their honest opinion of this girl, her attitude, her selfishness, and her inability to contribute or replace food she eats which others have paid for. Naturally, if he is "head over heels" in love with this girl, your brother is going to challenge whatever you say, but if it ends up three to one, and he won't agree to moving her back out again, then he should surely be given a compromise? Either he asks her to leave, being the one who brought her into the house, he stipulates that she must get a job and contribute within say, two weeks, or he must leave with her and continue to support her in the way he is. We both know he will never manage to do that for very long, because she isn't contributing. Maybe then, he will appreciate how important it is to put something into a relationship instead of taking out all the time. You then need to face her as a family, telling her the results of the Family Meeting, unless your brother can sort it out without too many problems. There's no other way but to tell her your decision, in a calm, but strict manner, and show her the door, I'm afraid, unless she can prove to you that she wants to stay by getting a job within fourteen days and adding her contribution to the general wear and tear of the house, laundry facilities, heating, bathing facilities and food. Don't let her walk all over you... show her you mean it, but in the nicest possible way. Brightest Blessings, in the hope this might help, and good luck with whatever you decide is the solution.

Why don't your parents just tell your brother to move out and take her with him? Give him the ultimatum instead of her. Sound like he needs to be responsible for her moving in and he should get his own place if they want to live together.

OMG, sounds like you are in a precarious situation. Since you and your parents pay the way there. I'd suggest you and them sit down and talk. After this include your brother pn another dicussion letting him know what has transpired in your meeting and your concerns. Apologize for not including him in the first meeting. But tell him your concerns. She needs to get a job! A time limit needs to be set. You could also give her the news paper and let her know that you saw some places that if she were working that she could move into. Set down ground rules in your home. If this does not work, then would you be willing to move? If so, tell your parents that you can no longer tolerate this behavior from this girl. Let them know you are willing to move if need be. Be courageous and let your feelings be known. Your rights in the home should not be a minor thing. As a family you need to come together. No matter how your parents feel about your brother, they do not want you to be unhappy. They do love you. By the way, I had a "guest" that I gave the news paper to and told him that I saw some affordable places for him. Likewise, this person was not contributing to anything in this home. He got the message and moved out with his next pay check. Best of luck to you and Bright Blessings.

I would have a big problem with this. If you live in my house you follow my rules. If it was my parents house you would have to respect them or be out on you butt.Your brother needs to open his eyes and speak up to her.If she cares for him she should respect his wishes.

if the girl is a pro, try collecting evidences that would pin her down. Also, try talking to your brother about this and tell him that your parents are no longer happy with what he is doing. If he intends to get serious with the girl, its better that he must move out of your parents house and live on their own. Tell your parents about what you feel too, Even if he is the apple of their eye, try your best to persuade them that you are no longer comfortable with the setup in your house. You are also their child and your brother and his gf are not showing you good example. tell them they would not want a daughter doing the things your bro's gf is doing. Good luck and pray hard that your big bro could get to his senses as soon as possible.
