How Do You Say Goodbye? — Margaret Burman

Lisa knows she should break up with Lawrence. He's not right for her and she knows it. But Lisa's got a big problem - she can't say no. To anyone. So when Lawrence asks her to go steady, she accepts (sort of) even though she's just met Alex. He's the boy Lisa really likes and wants to see a lot more of. Now she has two boyfriends but she's miserable.

Lisa wants to straighten things out, but she's afraid of hurting Lawrence. So she lives a double life of lies and confusion, trying to keep Lawrence and Alex apart. And it works - until the night when her lies go too far.
