Most Helpful Guy
Well if you didn't like the way he was the first time it's not going to change. It was a stupid reason to break up in the first place but that's just my opinion. You might just be sad that you're alone again (not necessarily missing him, remember you were "relieved and happy" when you broke up). Make sure if you do ask him back that it is 100% what you want without any doubt. It's not fair to him to ask him back and then realize nope, you were right the first time and dump him again! Keep in mind also he may not want you back either.
