Worries

So yesterday, my airman and I decided that we would get married before tech school is over. That means that sometime between now and October, I'll be Mrs. Martin. and I'm ecstatic! It's everything I've ever wanted, and I know without a doubt that I want to marry this man, the love of my life. But I'm scared. What if I can't make him happy? What if I can't handle the life as a military wife? What if he marries me, then a day, a week, a month, a year down the road decides he made a mistake and regrets it. I don't want to tell him. Not only do I not want to hurt his feelings, but he already has SO much going on right now that I really can't bring myself to add to his stress load. Am I just being paranoid? Did anyone else feel this way?
