<human>: Can you summarize the given text in a few sentences?

Hey everyone,

My ex girlfriend and I dated on and off for the first 3 years of college. I broke up with her because I wanted to experience more of life, and didn't want to be in a relationship through all of college. After we broke up, we continued to be in a weird, confusing half-dating stage that got real unhealthy for a year. It was unhealthy because she wanted to date, but I didn't want to, yet I didn't want her to leave my life because she was my best friend. 

Anyways, it is both of our senior year and we have both been trying to move on, not talking, hooking up with other people, and trying to give ourselves reasons to dislike the other person. 

However, I really miss this girl. She used to be my best friend and our personalities are so compatible. I only have 40 days left until we graduate from college, and then we will likely never see each other again. In this last 40 days, I want to end college on a positive note with her just like the way we started it. I guess I want to have an open relationship with her until we 
graduate. I know things were ugly for a while, so I am willing to put in as much effort that's needed to make things healthy again. Do you guys think this is a good idea? I think I would regret it if I never talked to her again, or if we both ended college with resentment towards the other person. How should I go about telling her this?
