POST: Me [M 22] and this girl [21 F] who I have been seeing for the past 2 months just ended things because she wants to give her ex another chance. 

I thought the relationship was going well but she then told me even though she still had strong feelings for me, she wanted to give her ex another chance because of their history together.  

Even though we were going out for only two months we had a strong attachment to each other, and finding it difficult to get over. 

Can anyone suggest ways that helped them get over a person after a breakup?
TL;DR: 
Girl I was seeing went back to her ex, finding it hard to get over it. Any suggestions on helping to get over a person?
