I did the same thing. I didn't break the pattern until I ended up with some bipolar guy who was emotionally traumatic to be with. I took many months off, although I still slept with people on the side like you. Finally I gave it all up completely. I had the best girlfriends in the world who I scheduled time with every week. I picked up new books, new hobbies, until I really stuck with a few. Took time to think about my career. I got a better job finally. I felt better about myself with that and was able to take more time for myself instead of use my small amounts of time to self medicate with men. Buddhism helped.

It wasn't until I was really hurt and felt good about my job that I grew out of it.
