Financial responsibility/division is something that should be discussed before the marriage, not after the fact.
Me, I have always taken care of myself financially, I have never been into comingling funds. My spouse and I would have one joint checking account that we each deposited into. The shared expenses were taken from that account, beyond that, we had our own investments, credit cards and so forth. I never expected a man to take care of me.
In the final analysis, for me, it was the best decision. When I read around this forum and others, it is obvious that too many women are too dependent on a man to support them. When the marriage ends the women are left destitute and have no clue as to how to support themselves or their children. When one is married to an addict, it is even moreimportant to have seperate funds, as an addict will strip one clean out of money.
Just my thoughts based on my experience.
