Is it wrong

That I want my best friend and her boyfriend to break up? She was a completely different person before she met him. She was independent, went to college, hung out with her friends (even when she was dating different guy). When she started dating this current guy, she started smoking weed, stopped going to college, and she is so afraid that he's going to cheat on her that she spends ALL of her time with him. She ignores me and her other friends and depends on this guy for EVERYTHING! She can't even call to order a pizza herself, which is something she would have definitely done before. I'm worried about her and I miss her a lot. Before this guy, she wasn't one of those girls who dropped all of her friends for a boyfriend. I'm just concerned that this guy isn't the best for her and he's gotten her into other drugs as well. She told me he used to sell cocaine.
