It's a new year and the feelings she once had, have been thrown away by the betrayal of his actions. She is doing everything she can to resist going back to him. The temptation is heavy because she is still seeing him everyday at school, plus he blows up her phone everyday. She did real good until the end of January, that is when she gave in. She loved him, he was all she knew. She just could not see herself with someone else. They got back together and things went amazing. He had "changed" for her, he knew that he could not be without her and knew that he was not going to find the love she was given anywhere else.
That was until the lying and cheating came back into play. At this time in her life, she did not know that this was going to scar her for the rest of her life. The feeling of betrayal turned into her not loving herself; her crying herself to sleep every night; her feeling like she was not good enough. It all taught her a valuable lesson.
Of course, he came to his senses for the 100th time that he just could not be without her. But this time, she was not having it. She did not care about how much he poured his heart out to her, the countless times he called her phone crying or the many times he brought up her taking him back the times before. She was done. She could no longer put herself in a position to hurt, to feel unwanted and unloved. Although in her heart she knew she would always love him, it was time to let go of something she thought she would have forever.
