I think it takes time to get over a separation. A month may seem an eternity when you are suffering, but it also feels like a minute when you are really enjoying being with someone. Maybe it will take a little longer and you are forcing yourself to be fine as quick as you can. And also, maybe you just have to understand that, even though you love each other, things got out of control and you needed some time and space to set your emotions clear. I would suggest that you try your best to be fine, to be positive and not to feel like everything is lost now that she's gone. If you both really want to be together, you'll find a way to do so. But the first step is that you rearrange yourself and get over all the issues you have that may have affected your relationship. Otherwise, you'll end up fighting and breaking up again. You should try to figure our what went wrong and talk about it to try and fix it as a couple, as partners.

Calm down, remember the good times and what makes you be happy together and then talk with her about it. But don't do it with tears in your eyes, don't do it desperately; talk from love and honesty and you'll see you can do wonders.

I do wish you two get back together and be happy again
