Why does my husband threaten divorce everytime he's gone for military training?

Basically my husband left for his 3 weeks of military training, he's still gone. for the first week or so, he was sending me all these lovey dovey texts, about how much he loved me and missed me. and then literally the next night for no apparent reason, he sends me a bunch of texts saying that he doesn't want to be with me any more and that he's not happy. saying he wants a separation. I was blindsided. i thought we were doing really good. He won't answer any of my calls or texts now. he's ignoring me. what kind of guy breaks up with his wife over a text, and then won't even talk to me or anything. couldn't he have waited til he got back from training in another week. He must have called his mother, and told her to go and get his stuff from our place. I told her no, i wouldn't give her the stuff. i'm not trying to be mean. but he can be man enough to come get his own stuff. i'm so mad at him right now. i can't believe he is putting me through this. we have two kids, been married for 5 years, and the least he could do is show me some respect and talk to me in person. So i'm going to demand he sit down and have a mature conversation about what is going on. i deserve some answers. i just don't understand. every one keeps telling me this is a pattern he does. every time he is gone for his military training, something happens and he gets distant from me and starts talking about divorce. this is probably the 4th time its happened now. but this time just feels more serious to me. i'm sick of getting jerked around like this. my question is, how do i handle this when he gets back. Should i try to get him to stay and do counseling and give our marriage a chance, or should i just let him go, and separate? it kills me inside. I love him and i don't want to lose our marriage. i just don't know how to handle this situation. some people say i should just play hard to get and ignore him right now, but i hate playing games. and other people say i should do every thing in my power to fight for my marriage. what would you do in this situation. sorry its so long. i'm very confused.
