How do you reignite the spark between you and your husband? Constant arguments due to finacial,work,kids. Its been straining our relationship alot. Any marriage advice?

Arguments are common even before marriage. My GF of 5 years likes to throw in surprises every now and then, to keep our relationship strong. I would do the same too to make it a mutual effort and sometimes we try to talk things thru other options like emails, text messages or even letters to get thru the argument without face to face contact so that we will be logical and lesser chance of reigniting the argument.
