The hardest choice and the best choice are quite often the same thing.
Stay single. Without wallowing in your misery, try to experience it as it comes. If you refuse to stuff some bullshit in the hole, it will heal faster. In the long run, you will learn more about yourself by going through the pain honestly than you ever will by running to the next relationship and drowning yourself in it.
Once you've fully learned a lesson, you will see it coming a mile away the next time, and you'll have room and time to figure out exactly what will work for you.
