What reason would my husband have to postpone this divorce???

Here is the obvious...he public humiliated me by openly having a relationship in front his friends and family. (still won't admit to me that he is seeing this girl) Well he basically posted his affair on the internet which gave me most of my evidence of adultery. Fact of the matter is that he is a Marine...there are consequences for the actions he took. Now he has to pay the price, he left me the day I asked him about this woman. Is he really surprised I filed for divorce after all of this foolish behavior. We are both young but I had his back for a long time...now in the past year he hasnt had a job and helped in a large amount of debt because of this. We are basically splitting the debt even though if he had been working we wouldnt have the debt at all. This is so tough but what else am i suppose to do.
