I recently got out of my first and only relationship (the details of which can be seen in another post) and now I am quite confused on what to do next.

I have asked a few friends and family members, and unsurprisingly they have told me to try again. Emotionally, trying again sounds tempting, but I rationally know that it is a terrible idea. I shouldnt have gotten involved in the first one.

However, I am currently unable to completely shirk my emotions and thus the idea of trying again, and I need to hear the case from this side again.

Thus, I'm asking for help - how do I rid myself of attachments and emotions to live more rationally and avoid the pain that is guaranteed with a relationship? I can't figure out how I managed to gracefully pull it off beforehand, and I desperately need pure, cold rationality back.
