Hello everyone I'm a first time poster and I wanted to ask you some advice before I did a stupid thing. My girlfriend and I were dating for 4 years until a few months ago we broke up because of some problems. At first we just kept talking to each other because I wasn't sure that it was serious because we broke up 6 times before and we always got back together so I just gave her some time. Until my friend told me that she was flirting with other guys so I contacted her and asked her if it was true and she said yes so I can get over you and stuff. She did not tell me that she has been speaking to this guy and that she likes me but she has actually asked to see me a couple of times and spend time with me. She said that she wants to be friends and values my friendship and everything and that she just wants to try other guys because she had been with me for 4 years.
I have been feeling quiet bad lately and I want to just start feeling better again because I feel that we can no longer ever get back together. I don't know whether shes trying to get back at me using this guy but they have met together on a friend's date and tomorrow I will see her. I have prepared a final goodbye letter to give to her but I'm unsure whether to say one final goodbye or stay as a friend. So I would like to ask you what should I do?
