You're married under the eyes of religion and not the state. Neither party will be at the mercy of lawyers or the family court. At worst, the dude will have to pay child support for his offspring. No losing the house (if either owned it outright or it's in one person's name, not the others), no splitting of assets, no splitting of retirement. If she refuses, no problem, she's only in it for the exit fee. If she goes a long with it, then you have a keeper.
Ultimate litmus test if a female really wants to build a family with a dude or not. The alternative, ALL THE TIME is:
Splitting of the marital assets.
Losing the ability to stay in YOUR house, but having to be forced to pay for continuous upkeep, insurance and taxes even though you do not live there any longer.
Splitting of YOUR savings.
Splitting of YOUR retirement accounts.
Loss of ALL tax benefits, while she keeps the child dependency credit.
Having to pay alimony, without having the ability to write it off on your taxes; yet her alimony payments are tax free.
See the difference?
