BAD advice to go back with same person! Best advice is to MOVE ON! Why do you have two eyes and one mouth? I heard this clever question from somewhere. Makes sense. If you say just to doubled looking forward ahead? That is the correct answer. You have one mouth to say something but two eyes to look forward. You do not have any eyes on the back of your head! That is why its important to go forward, not backward!
That is why it is not good to go back with same person. I had one who wanted to come back often back in the 80s. She lives in next state and she is deaf. We went to same pre-school but her parents split and she moved with her mother to another state then she found me through an old classmate of ours. Then we dated then one month later, she asked me to marry her and I told her no! I was 17 and was still in high school for one more year. I wanted to focus on school. Made the right move! Whew! Then she dumped me 2 months later because she was upset for my answer and could not wait to marry. Few months later, she apologized and wanted me back.. ok ok.. another chance. Then dumped..
To make it short, she tried one more time six years after I was 17. Do the math. I was going back to college and she wanted me back by marrying me! I told her NO!
Then she threated me by marrying someone else and she found him a week after I dumped her then got engaged 2 weeks later then married six months later just to hurt me.
2 years later, she wanted me back!! A married woman!!!! YIKES! I had my friend with me in person because she came in town to see me! But she kissed me!! I had to push her back! And ignored her. She was sad and gone back home to her estranged husband. She told me it was communication problem
Then 5 years later, she divorced him and wanted me back! I told her NO! Why? She hurt me first time by marrying wrong man and I told her to wait for me to finish college first then consider marriage.
So, my advice is NEVER go back to the same person. Maybe that person has OCD like my ex? She does have that problem and her mother knows that. In fact she did tell my mom about my ex.
Now I am happily married because we worked together to make that work. Sure we had 3 times "break up". It was more of misunderstanding at that point. First was fustration and needed to cool down but we were back quickly before it became cold. Second was miscommunication but we worked it out. It is not the same as what you described. Third was she was on vacation with her friends for a week and it was fustrated that I almost gave up but it was okay when she got back from her cruise with her friends.
