Rachel Berry knew that she had many highly detestable personality traits. She is high maintenance, a perfectionist, obnoxious, sneaky hot, has a pathological need to be accepted, conceited and perhaps too loud for her own good.
She also knows that sometimes these rather offensive traits tend to over cloud her better personality traits and despite what people do say; she does have some good ones.
Her best one being that she is actually quite forgiving.
Many people would disagree yes, but that is because they do not notice her good side. They choose to only see the bad as it makes them feel better about their own bad traits.
She forgave Finn for everything. The drive by egg throwing, choosing Quinn over her, then choosing Santana (and even Brittany) and deep down she has even forgiven him for lying to her about Santana, though she isn't quite ready to admit it aloud.
She has even forgiven her fellow Glee members for not realizing the talent they have with her. They are too busy to try and steal the spotlight for themselves, that they don't see that they really do in fact need her and the talent she owns.
God, she has even forgiven Shelby. For thrusting Jesse into her life and giving her a little taste of what paradise feels like and than ripping it away from her without even flinching and like always, choosing Quinn Fabray (well Quinn's daughter) over her.
Rachel figures that if she doesn't forgive people in her life, she would have an even more lonely existence than she does already.
She decides to spend time to herself. Being with Finn had clouded her dreams. She can't remember the last time she spoke about becoming the star she know she is destined to be. She digs up her animal sweaters and starts to let her bangs grow out. She never realized how much she missed the old Rachel Berry until she was forced to look in the mirror without having someone standing behind her; telling her what they wanted from her.
Rachel finally starts to catch sight of the person she use to be. The ambitious diva who everyone detested but deep down respected.
She was happy being single and discovering the old Rachel.
Finn was the only one who ever really bothered to email her, so when she comes home from ballet to find one new message flashing on her screen, her heart skips a beat for a minute. Maybe Finn was ready to forgive her or maybe he just wanted to talk or just something.
She dropped her bag to the floor, her heart still thundering in her chest as she clicks open.
When she sees the email address flash onto the screen, her heart stops thundering and merely sinks.
Jesse St James.
Of course he would sneak back into her thoughts when she thought she was finally doing ok by herself.
This world was an orchestra.
And right now Rachel Barbra Berry didn't feel much like the conductor.
