Am I wrong for telling my friend his “woman” is a manipulative narcissist?

I say “woman” because he refers to her as his friend but she’s actually his sugar mama basically. She controls every little detail of his life, and in all honesty I don’t care very much. He made his choices and he’s mature enough to take a stand if he wants to. But he always complains to me and vents how he wants a normal relationship with someone else, an actual wife and kids. He said she says she understands and tells him to live his live, yet at the same time her actions makes it impossible. She clings to him any time he asks for space, not only that but she reached to his home and just sits there and wait for him to get home. That’s kinda creepy. I told him I can’t give any advice but it seems to me that she’s a narcissist and she’s manipulating him, and that her words and actions aren’t aligning. I told him her current attitude and actions are telling me that she’s capable of sabotaging any other relationship he chooses to have with someone else. He doesn’t believe it. So I don’t say anything anymore. Was I wrong?
