Do you want out of the marriage or do you want to stick it to him? If you simply want out of the marriage, here is what you do.
First, DO NOT GET PG!!! That stops all divorce actions in all 50 states. Get on the pill if you are not already on it and cut off the sex!!
Get a lawyer and file for divorce. If you were living in the house before you met him, it is PRIOR property and the Texas community property laws do NOT apply. He does NOT get half. (Unless after you got married you put the house in both your names.) As you file, ask for a court order that he move out because you fear for your safety. Start by filing for divorce for reasons of incompatibility. You do not have to prove he cheated or anything else and do not even have to mention it. Simply file for divorce.
If he wants to fight it, HE will have to hire a lawyer. At that point your lawyer can inform his lawyer that if he contests the divorce, the adultery will come out. If the adultery was done with another military member or the spouse of another military member, tell him that information will be given to the service for an investigation. I would bet he would not want that and will want out of the divorce quietly so his career is protected. In that case, you can call the shots, getting your house, horse and car back.
On the other hand, if you want to stick it to him, you are going to have to get him to move out of the house. Simply stop all that wife stuff. Do not shop for him. Do not cook for him. Do not do his laundry. Do not take care of his uniforms. Do not clean the house. Do not do ANYTHING for him. Leave the answering machine OFF and do not take messages for him. Sleep in another bedroom or on the couch. NO SEX. On the first of the month, go down to the bank and take all the money out of your joint account. Open an account of your own and put the money into it. You might get to do that one or two months at the most before he also opens up a new account. Do not forget to clean out the savings account. In the meantime he will not be able to pay his bills. Creditors will start coming after him. (You pay YOUR bills with the money.) Call the bank and cancel all of your joint credit cards. Get one that is in your name only. Get a job because once he stops the bank payments you will get no more money from him. Consider taking his prized stuff (specially guns) and go down to a pawn shop and pawn them. Leave the pawn tickets where he can find them. If he goes and gets them out of hock, pawn them again. If you have another key for your car and your name is on the title, simply go get the car. Since it is your car, you are not stealing it. (If it is entirely in his name then leave it alone.)
Eventually he will get tired of the whole thing and will either be more than willing to give you the divorce OR he will move out of the house. If he moves out, you file for divorce immediately saying he left you. Hold the adultery stuff as the ace in the hole, as mentioned above.
If at any time he hits you, you call the cops. If he forces you to have sex, it is rape. Call the cops. If he is gets charged with domestic battery or rape that could end his career. He may be more than willing to divorce you if you agree to drop the battery or rape charges against him.
As far as that adultery stuff, hold that as your ace in the hole. Do not file for divorce for adultery!!!
Bottom line, do not let him have his cake and eat it too. He either treats you like a wife and remains loyal to you or you are nothing and he gets nothing from you. Let him see just how much nothing is.
(Personally, I would advise you just getting out of the marriage by the first method suggested. He could get violent and you might not survive the second.)
