We could easily work out different schedules for our jobs and be able to move on from this but this other guy won't leave her alone. He is constantly texting her and bringing her gifts so it is almost impossible for her to move on from him. I am willing to forgive everything that they may have done if it meant that we could still be together

I went through the same thing in a relationship of 5 years. Her and I worked opposite schedules and both went to school full-time. One day she told me she wanted to take a break because she met someone else. I cried like a little baby and begged her not to leave. I texted her all the time and called her way too much. She would tell me that we are together for good, then leave the next day and go back to him. I kept getting the advice "just leave it alone, if it's meant to be, it will happen. If she loves you, she will choose you", but I couldn't leave it alone, I loved her! After 3 weeks of no sleep and near-insanity, I decided to "leave it alone" I went out with my friends one Friday night and didn't text or call her once. I woke up the next morning hoping and praying she might have texted me..but nothing. I didn't talk to her all day Saturday, then Sunday she texted me and said she was coming to move all of her stuff out of my house. I left the house and I wasn't anywhere to be found when she did so. Monday night she called me to talk, but I acted like I was too busy. Tuesday night she asked me if I wanted to go to the movies and I said "sure" (like it was nothing special, but I was so happy). After the movie she stated talking about getting back together (AGAIN!) and i said, I'm sorry, but I can't. You broke my heart and I can;t go through this again. She then told me she made the biggest mistake ever and she was sorry. I told her "I don't know, i just can't go through this again". She started crying and begged me to take her back and I did. We are good now and she regrets everything she did. Morale of the story, take the advice: leave it alone, if it is meant to be and she truly loves you, she will choose you. Don't be an ass and act like she means nothing to you, but leave it alone, let her contact you.
