<human>: Over a year ago, I cheated. I was in a relationship that I knew would end. I drank too much. She was two days fresh out of a high school sweet-heart relationship. I always thought she was cute, but that barrier had finally dissolved. I immediately returned home and told the previous relationship the awful thing I had done with Myrtle. 

This was the start of a 6 month relationship. Myrtle and I had a lot of fun. We exchanged love and laughter. However, I felt that something was missing. I knew that I needed to sew oats and grow on my own. So, I broke up with her. She was devastated. I felt extreme guilt. 

We moved on, in most ways. I relied upon myself for many months. I was happy. It wasn't but a month ago that an old friend asked where my girlfriend was  and I said that I was "single and happy". Three weeks ago, I felt an itch. I reminisced over the summer before. I had these feelings every so often during that time.

On a whim, I barged right back into her life. I asked if she wanted to talk. I told her that I missed spending time with her. She looked me in the eye and told me that I had hurt her. And, without proper thought or care, we laid back and watched a movie. I then told her that I wanted to start spending more time together. A relationship wasn't not what I was looking for. I could not promise forever, but I was "stable".

Here I am. Three weeks in and the same feelings resurrect. I know, again, that this relationship has no future. I enjoy spending time with her, I believe, for the comfort. I felt uncomfortable for a moment and swiftly snatched her heart back for abuse once more. 

I want her to understand what I am. I am "that guy". The one who tramples everything in his self-absorbed wandering. That, though I do not necessarily want to see her leave, she will undoubtedly be hurt if she does not free herself.

I'm grasping for a solution. A solution apart from the one I know.

Summarize the given text in a few sentences.
<bot>: I continually drag others along, knowing they will be hurt in the process. How do I stop? Starting with my current rekindled relationship.
