My 14 years old stepson and I are not getting along well...?

My step mom and me didn't get along that well either but she was mean. He sounds like a 14 year old that has his mom putting **** in his head. I would try not to stress out and give him the space he wants. When he matures, he will realize how wrong he was for being disrespectful. I wish i could help i hate snappy little teens my sister is one now and choking them seems so necessary (KIDDING!).
