Melanie left Jake for a reason which was he was drunk and did not pay attention to her. She needed someone to love her and treat her like a queen and that someone was Andrew. Andrew loved Melanie and Melanie loved Andrew. Even though Andrew's mother disapproved of their relationship, Andrew and Melanie truly loved each other. Melanie deserved to be with Andrew because Andrew would have never hurt her the way Jake did. Melanie ending up with Andrew would have made me so much happier. In her heart, I think Melanie was scared to love Andrew because she was afraid that he would hurt her the same way Jake hurt her. Andrew is the one Melanie should have ended up with Jake.
