To restore any chance of salvaging your ailing relationship, it is essential that you get your ex out of your head, at least for a couple of weeks. This is of-course a very obvious thing to do.
But you say, I cannot live without him. The big problem that arises after every breakup is that there is this great void that has settled inside of you. In your apartment, on the street, at work: it's crazy that the vacuum or hollow feeling trails you every where! Now is definitely not the time to ask the question when will he propose, but the truth is that you will only increase your chances of wining your man back if - and only if - you start to show a little more interest in yourself.
I'm afraid That He Will forget me
If you indeed want to save your ailing relationship, you would be at least hoping that he'll forget the bad side of you. Indeed, it would also be to your advantage to omit the unpleasant moments that led the both of you to this present separation.
Take a step back in your love life: do you have fond memories of your ex left? This is a fundamental requirement, but of-course you may not have much left because he had more flaws than qualities to you. In any case, this led to the end of the relationship. Your goal is to recapture him, and to accomplish this you'll have to forget the bad memories and replace them with good ones.
Why do not you listen to kindly advice? Because thinking itself is not enough: as we think we do not act. I would say instead: "Act for yourself! "
Nothing is more effective than taking action. Precisely because when we act, we do not have the time to over-think or over analyze things. And at least, positive thoughts were fed! But no, it continues to do it again and again the film of the fall of your relationship.
