As the mother, you are always going to feel some sense of guilt for your actions. However, the law was laid down regarding the rules of the house. He is 18 years old now and completely aware of how to accept those rules. If those rules are broken, he must deal with the consequences. The drinking and having girls over the house is being done behind your back most of the time and is completely unacceptable. Since he is still in school, it would be in his best interest to let him stay with you until he graduates. Since he has a part time job, may be he could find a room mate and move out after graduation. I think that would give you a great deal of peace. He is at the age where he will rant and rave to try to get his way. The best thing that you can do right now is simply to listen. Your previous actions were not wrong at all. Keep stating the rules of the house!!! He probably will not change his behavior any time soon. What I could suggest is that you seek professional help from a neutral source like a psychologist and/or a family therapist for both you and your husband on how to deal with this situation and you would have the opportunity to completely express your feelings and receive practical coping mechanisms. Your son could benefit from the sessions as well, however he does not seem to receptive to many suggestions. This situation will definitely take some time to resolve but you can and will get through it. Thank you and have a great day!!!!
