What will happen to my husband for going awoll in the marines?

my husband survived going to parris island and then his school of infintry...but its when he got to the fleet that all his problems began...he was placed in a platoon where all the lance corprals thought that they were gods or something, because they would haze the privates "boots or Jews"...which my husband was at the time. And a couple of incidences happened where over half of the Lance Corprals got sent to the brig for the hazing and beating up of the "boots" and the Lance Corprals that were left and didnt get sentenced to the brig said that they were going to make the "boots" life there a living hell for the remaining time that they were enlisted....so the threat realy got to my husband and he was in fear so he desided to leave or go awoll...so the first time he left, he packed up our stuff and we went back to GA and he stayed gone for 28 days and then decided to go back...but when he returned nothing happened to him at all and he wasnt punished at all...so after talking to some people who went awoll before he heard that if he actually stays gone long enough to be considered awoll and then turns himself into the regular police that he would just have to spend 30 days in the brig and then get court marshalled and be discharged with an "other than honarabel" discharge. So is this plan 100%...or should he have not listened to those other people that told him to do that? he has already been in the brig for going on 3 weeks now and he hasnt been able to give me any phone call or anything...is that normal? Are they not alowwed to make phone calls or write letters while they are in the brig?? Did he make a mistake by going awol? i mean he didnt realy want to become a marine untill he was convinced by a recruiter....which the recruiter had lied to him and tricked him into joining...so for all you haters out there that call him a or a coward or whatever...dont judge him cause he was lied into joining...he was going in for mp and he ended up getting infantry! Its a very hard lifestyle to get into especially if your in a realtionship, and he thought by going awol it would help our life for the better as well. And i just want whats best for him. So please dont judge him...please just help us by answering my questions please.
