      According to a recent survey on money and relationships,36% of people are keeping a

bank account from their partner.While this financial unfaithfulness may appear as distrust in

a relationship,in truth it may just be a form of financial protection.With almost half of all

marriages ending in divorce,men and women are realizing they need to be financially savvy,

regardless of whether they are in a relationship.

      The financial hardship on individuals after a divorce can be extremely difficult,even more

so when children are involved.The lack of permanency in relationships,job and family life

may be the cause of a growing trend to keep a secret bank account hidden from a partner,

in other words,an"escape fund".

      Margaret's story is far from unique.She is a representative of a growing number of

women in long-term relationships who are becoming protective of their own earnings.Every

month on pay day,she banks hundreds of dollars into a savings account she keeps from her

husband.She has been doing this throughout their six-year marriage and has built a nest egg

worth an incredible$100,000.Margaret says if her husband found about her secret savings

he'd be hurt and would take this as a sign that she wasn't sure of the marriage."He'd think it

was my escape fund so that financially I could afford to get out of the relationship if it went

wrong.I know you should approach marriage as being forever and I hope ours is,but you

can never be sure."

     Like many of her fellow secret savers,Margaret was hurt in a former relationship and has

since been very guarded about her own money.

     Coming clean to your partner about being a secret saver may not be all that bad.Take

Colleen for example,who had been saving secretly for a few years before she confessed to

her partner."I decided to open a savings account and start building a nest egg of my own.I

wanted to prove to myself that I could put money in the bank and leave it there for a rainy

day."
