I don't understand the point of a Q like this. I know you're probably mad at him for breaking up, but think about this logically for a few minutes.
1. Whatever you could do, how would you ever find out he regrets losing you?
2. If he broke up with you, do you really want this guy back - someone who did that - and risk him doing that again?
Your best course for the future is figure out YOUR part in the relationship that may have lead to it breaking down. Realize how to correct YOUR actions, so the next relationship you have goes even better. Forget about this last guy. For whatever reason, that's history. Take some time to relax and enjoy your life going forward.
If you are still worried about what your ex-boyfriend thinks or feels, you need to think about whether you are really ready to be finished with him and move forward.

I think the best thing you can do at this point is just let go and try not to be obsessive. If the relationship ended, it tells you that there is something you should work on, so my advice is to focus on yourself - start working out, go out with friends more often, go to events that you like and who knows. He might see how together and happy you are and how well you are doing alone with yourself and regret that he lost you. It’s a win win. You take care of your happiness and you make him regret that you are no longer together. Good luck!
Live your 'new life', find things that make you happy and do them. Set a few goals for yourself -- and work hard to achieve them. I have never met a boyfriend who didn't at least on one occassion (usually more) regret losing someone he loved. So make sure that when and if he looks back and starts to think about you, you're going to be in a really good place and not just sitting around waiting for him to come back around.
