ive been in this situation b4. its been a lot of times but always with the same person. Whenever I see my ex-boyfriend its hard to look at him because you remember all the things you had together. But what I did, and maybe it will work for you, I sat down and I thought. For almost 2 hours I sat and thought. About my boyfriend at the time and my ex-boyfriend. And I thought Who do I love more? And what honestly went wrong in that relationship? And if it didnt work then, how do i know it will work now?
