I am a 42 year old divorce' and I live with my boyfriend of 4 years. I have a 20 year old son who is in college. My boyfriend has two boys..19 and 16. Thier mother has been offered a job out of state which she is going to take as she has been unemployed for 3 years. The 19 yr old works and is also in college, and he is moving in with a friend. Tyler, who is 16, will be coming to live with us. He has developed some very bad habits such as skipping school, as well as being allowed to come and go at his leisure. Pretty much allowed to do whatever it is he wanted. When he comes to live here, not only will this type of behavior not be allowed, but, it will become virtually impossible for him to just go off to a friends and such as we live further away than he did. I fear this will cause anger and animosity toward his father and myself. I am very concerened for all parties, and I am looking for ways to help diffuse the issues and try to maintain a healthy ballance and relationship between he and his father and myself. I have known Tyler since he was 12 and he is a very sweet boy and I dearly love him as if he were my own. I do not want to take his mother's place, and I will not be doling out discipline. I just want to be there for him and want he and I to have an open, honest, and hopefully close relationship. Any advice I can get will be much appreciated and helpfull.
