2nd Degree Domestic Abuse & violating no contact/Any idea on sentence?

[Mypast?]

Friend in Missouri has been in Jail basically since mid January. He has been charged with 2nd Degree Domestic Abuse (his wife testified that he pushed her after she told him that she was leaving him) and then he resisted arrest. This is the first time he's been charged with either. Any idea on jail time. I fear that he will do something drastic if he gets bad news. He knows his reaction to her news was wrong, so no need to really bash him for it. I just thought I'd see if anyone had any idea of time he's looking at.

When he did bond out he broke the protection order by calling once, writing to her once and going to see her once, so those charges are pending in another county as well.
