Hmmm...sounds to me like maybe he has some trust issues?
I certainly think it's a smart move for both of you to make sure you are finacially set before starting your new life together...just so long as he is making the same efforts to save up and pay off debt as you. Finanical strain can be one of the most stressful and trying situations, especially on two people who are newly trying to find their groove as husband and wife. But again, the street goes both ways.
Go with your gut girl. There is nothing wrong with making sure you are looking out for yourself in this situation.
