Don't get discouraged. Several months ago I felt like my ex wife would never get back with me. Now we are back together and working towards reconciliation. Believe me, it felt like an impossibility, but I kept fighting for our marriage even after divorce despite the tears and sleepless nights. Whatever you do - don't give up so easily. The road to reconciliation is a tough one, however I think you have a really good shot.
The best thing you can do is to work on yourself - to make yourself attractive. In many ways, it is almost like dating, except you are trying to win your wife back rather than date other people. However, the same concepts apply. Appear and be confident around her. To show her that you have you life under control even when you feel you don't. It also means being a gentleman and learning how to flirt and start up a conversation/listen. Flirting and conversation are skills that are easily forgotten if we don't practice them on a continual basis (one that I am still learning). It is also important to show her that you love her, but not through words and being needy. But by being there for her on her terms. That is tough, but it has to be that way. If you can learn to show her that you want her to be happy no matter what, that will go a long way in saving your marriage.
I can't tell you how many times I felt like I was making no progress, but you don't see what's happening in the inside of your wife and you need to ahve patience to stick it through even when there are no visible signs. The best thing you can do right now is work on yourself and to be there for your wife when she needs you. However, do not be pushy and try to make something happen. Overtime, if you are consistent with your behavior, she will come around.
