Hi my birth is 03/02/1983 and my husband is 04/04/1979, since we were married on 24/12/2011, we were facing many problems especially financial problems but we're both always encouraging and loving each other. How to make our relationship last forever and getting better especially in financial matters? we'll gonna have a baby girl to be delivered which is due on May 2013.
