Hello Broken_Wing,

It will be up to you to determine how much time and effort you wish to invest into this online friendship.

Although you are not the S.O. of this person reading this link The Manual ---The Significant Other's Guide to Dissociative Identity Disorder compiled by Jeff Vineburg or downloading a zipped copy of this file (98k) could be helpful in better understanding an outsiders perspective of DID.

Toward the bottom of the page he lists some online resources and a good book list.

Remember to keep your own boundaries strong and make sure your needs are met before you reach out in friendship to someone in need.
