Ok, did it again. Sorry Ashley1878, I didn't read your second post before posting my first. After reading the second post it gives a little more clairity.
Have you considered that maybe your husband is detaching so he can leave without feeling all the pain of separation? As I understand, it is a pretty common reaction with soldiers. He is going into combat for a third time, and I'm sure you know how scary that is.
There were stricter policies on re-deployment and time limits before. The rationale' was that extended combat time and more than a couple of deployments were too detrimential to a soldiers emotional state, which would render them less effective on the battlefield, ultimately resulting in more loss of life. It could be, that his detachment has nothing to do with you at all.
With all of that said, I would be wrong not to tell you this. A relationship is a fragile and delicate thing. It should be handled with as much care, as you the love you feel for your husband. Anytime there is yelling and screaming it is detrimental to the integrity of the of the relationship. It creates wounds sometimes that do not heal, chipping away at the bond that you are working so hard to keep. When you are yelling, you are not communicating nor does the other person hear you. It is only serves to hurt both of you, and causes undue stress.
I can't imagine how it feels to be fighting with the one you love, knowing that you may never see them again. That goes both ways, but imagine if you were him, and trying to get you mind in the right place to go to war. Whoa.
As far as the previous men that cheated on you, more men cheat than don't. Don't you watch the news girl. Sometimes they just can't help themselves. It's not a reflection on you. But, I can say they are less likely if the relationship is not in turmoil. It's very common with younger men, you know hormones and all. Sometimes they just do it to do it, and sometimes you can push them right into another women's bed if you give them too much grief.
To be fair women cheat too, but usually because they are not satisfied emotionally in their relationship. Men, especially young men, any excuse at all will do. The wind blows on the right spot, the conquest, the chase, revenge. You name it. The point is, it's not about you. Knowing this, will help keep you from bringing that hurt to your next relationship. Also, remember jealously is one of the most evil emotions. Don't be that girl.
One last interjection; I don't think lawdawg was advising you to excercise to loose weight. I think it was more on the lines of spiritual furfillment. It completes the trine between mind, body and soul. But, I can't talk either, l yoyo too. Lord knows my butt gets bigger, and athough I know lawdawg is right, I'm still sitting here right on it. lol
Hang in there
