Not to be the devil's advocate here, but while it doesn't matter what your ex thinks, it is worth considering protecting your identity on the net.
Your employer, or new employer if you apply for a new job, or your co-workers can google you. Some of what we say could be gossip fodder, and be a source of stress in a job, or be harmful to our families. Our surviving children. Anyone can access this site. ANYONE. A lawyer may not be telling you now not to post stuff, but if there is a legal battle down the line for anyone for any reason.............well, trust me on this one, it could get ugly. Stuff you type can be twisted and taken out of context.
I choose to continue to type what is bothering me, but take steps to protect my family's identity. So I get the support I need, while protecting my living children and beloved husband. I'm not telling anyone else to do this, but it is worth considering.
