Hello,
I agree with OronD. If you want him that bad, it is time that you are the one that is hard to get. Men are very different than women. They do like a challenge. Women think being sweet and kind will get a man, not true for most. If his feelings are true for you, he will be back but if they are really wanting this other woman, I say move on {I know that is easier said than done} but....He will NEVER be emotionally free for you. So ask yourself this: Do I deserve better than this? Do I deserve 100% from my partner?
All My Best
