Run! I'm sure the Ex doesn't know a damn thing about the open relationship. You are probably a branch she is testing to see if she can swing over on to in case the Ex situation goes south. Abusive EX attachments that defy logic, ruin relationships and marriages all the time. Just don't involve yourself with her. Tell her to look you up once she figures her shit out. Otherwise this will ruin your life. Just walk away now!
Your daughter is an adult, you can surely help her financially get situated somewhere else
Or let her live with you. Cut the shit
Grow a pair and end the marriage if you intend to be with someone else.
