I think they blame because they are not willing to take responsibility for their own actions, and the consequences of those actions. Although they may deny it if challenged, they feel like victims of external circumstances and not in charge of their own lives. The buck stops with us, and they want to play pass the parcel.
If you have a partner and children your primary responsibility, if nothing else, financially is to them. This is not a matter of opinion or 'unfair' laws.
To try and make us feel bad about this simple and objective reality is actually grotesque. even if they believe they no longer love us they have no right at all to deny their financial responsibility.
