No, not at all. Actually, when you do the Broken Circle quest you can find the "Black Grimoire" in the Senior Mage Quarters. When you give this to Morrigan, she'll read it and then when you talk to her again later she'll tell you that she's found out bad things about her mother and she'll actually tell you to kill her, and that's her personal quest. But really, you should've already slept with her by this point because, unlike Leliana, if Morrigan likes you TOO much, then she won't sleep with you.
