Seems like you liked him because you couldn't have all of him. He was a challenge.

Sort of that thing a lot of us go thru when we are just starting to date- and go for the "bad boy."

But as time goes on, experiences are lived, mistakes are made, and coping tools and learning curves are created and learned- we learn to date guys who are better than the last guy we dated.

Perhaps you never taught yourself or was able to attain the tools that tell you that you need to stop dating "bad boys."

You need to stop analyzing yourself in terms of what you did wrong to him. You know that the problem is not yourself and it is him. He will more than likely- be back. He found a girl who will take his crap- (no offense.)

Look up the 180 rule for breakups. It's about how to force yourself to move on, faking it until you make it.

You have to learn the tools to become a happier and healthier you. You sound very codependent. You get emotionally invested very quickly and make the guy your world and everything - very quickly. And this apparently is not making you happy- bc two breakups later- you want better. You want different.

Follow the 180 rule. And when you're okay enough. Diversify your life with other interests besides dating. So that when you start dating- you have more hobbies and social life. Make it a rule that the first 2 months involve only seeing the guy 2x a week.

It's not fun going thru a breakup. We have all been there- it's up to you if you want to put the proper tools in your life box to fix these problems.
