Can Someone Help Me With This Marriage?

I would stop those phone calls right away.  It is not fair on your husband.  If you had doubts you should have waited until your ex got back from Iraq and not gone through with the marriage.  The ex will seem exciting - it no doubt will wear off and also he might have to go away again.

Well if you think that you love your ex more then your current husband, you need to tell him. Don't keep dragging him along if you have stronger feelings for another man. He will probably be upset at first, but later on down the road I think he will appreciate that you have told him the truth more then anything. I really hope that all works out for the best for you. =)

You have made a vow to you're husband and to God.
Till death shall you part!!!!!!!  "the only grounds for divorce is fornication" says the bible.
You'r poor husband it's not his falt you'r ex came back and that you broke up in the first place.
What if things were reverced, what then?
If you truly love him you will stick to him and be faithfull.
Consintrate on all his good qualities and think back at what made you fall in love with him in the first place and made you accept his proposal.
Hag in there girlfriend.

Your ex has put you in a right spot.  Before you do anything you need to make absolutely certain what your options are.  If you end a happy marriage with someone you love to be with someone you loved before them, will you be better off than you are now?  Will your ex be going back to service and repeating what broke you up the last time?  If your ex was that keen for you to move on, is he indeed actively trying to pull you back, or is it just your interpretation of things?  I would have to suggest that you should be open with your husband about your current feelings.  It is unfair to hide from him the fact that your heart is now torn between him and someone else.  My advice is to talk to each of them separately and try and have each of them give you the advice you are looking for.  At the end of the day only you can decide what you truly want, all I will say is: If you have found a steady, truly loving relationship with someone who values you and respects you then you are one of a lucky few.  The reward for throwing that away would have to be something incredible if I were to even consider it.    Good Luck in whatever you decide to do.
