I think you should share your concerns with him because that is the honest thing to do. However, you cannot change him. Only your boyfriend can decide to change his life. For his sake... I hope he does. He has already grown up with a very bad environment, and he is surrounded by friends who live a dangerous lifestyle. So, his "normal" is already a thousand times different from other people's view of "normal".
Just seems like a very volatile situation, and one that I would suggest you look long and hard at. You don't want to be pulled down with him! |
