Nope. Love paternal, protective Angel with everyone. It's one of his best qualities with Buffy. She needed that.
Buffy's strong, but that doesn't mean that she doesn't need to be stood up to sometimes.
She is someone who needs someone to talk to about her issues, someone to go to for wisdom when she needs gentle advice or comfort and who will also tell her all the things she may not want to hear, but needs to. Angel may be stuck at the age he was sired forever emotionally, but he still has the wisdom of his years with those experiences and perspective on all the things he is missing out on by not being human. Buffy often is in a position where she feels completely alone because everyone looks to her to lead and protect them, while Angel is the only one who faces the same thing and is actually saying he wants to protect her, even if he feels like he has failed to do so (emotionally, not just physically). Buffy doesn't want to be strong all the time. Sometimes she wants to still feel like a normal young girl who is still learning and not just the Slayer who is expected to have all the answers. Angel focuses a lot on protecting the human side of Buffy from the life of a Slayer; that's his world and he doesn't want her swallowed by it. He's always reminding her to live her human life, too. She's also feeling the loss of her father after the divorce, she can't talk to her mother about much of anything (especially when she wasn't in on her secret identity) and she can't talk to Giles about things that are personal like romantic insecurities. Willow isn't her sounding board for all of it.
Angel isn't a subordinate and he has a strong separate identity with opinions of his own. Buffy is still strong in the relationship, was the one who pushed for it at every step and was the one who began the humanizing of Angel. She is the one who ultimately teaches Angel how to be a hero and creates his desire to become part of humanity and fight for it in the first place, even if he ultimately takes his destiny into his own hands (which he had every right to do). Likewise, Buffy proves she can make the hard decisions that go against everything she wants when she has to, as well. That's why they're actual equals and he's not yet another boyfriend of Buffy's who is a subordinate follower, not a leader.
