Advice please!?

You need to have a serious talk with your mother. Not to be offensive, but she is acting quite irresponsible. For one thing, I'm hoping that this guy that she is allowing to live in your home was checked out thoroughly before being allowed to move in. (you know, criminal records if any..things like that) Again though, you need to have a talk with her. You need to tell her how neglected you feel and why, and how much you are hurting as a result. You should also, while being respectful, tell her exactly how you feel about her not coming home at night. I would explain that as a mother it is not a good idea to not come home to your children at night. It is not safe for you and I'm sure it makes you worry about her when she does it also. If talking with her doesn't help I would suggest meeting with a counselor, but that costs money and I know that is probably not a very reasonable solution for you all right now. In the meantime if talking doesn't resolve it what you could do is try talking to a school counselor or even searching for forums or message boards online that are for people in family situations similar to your own. Maybe getting to vent your feelings in a place where there are others in a similar situation might make you feel better. I will stress on a final note that this isn't your fault. Your mother sounds as if she has some issues of her own that she needs to work out that have nothing to do with you. I hope things work out for you. :)
