My issue isn't with the bio mom however.
I'm wondering as the stepmom, what sort of relationship is ok regarding my husband and the ex. I know they have monthly meetings, and call or text several times a day.. But my husband insists these text messages are private, and only talks to her on the phone when I'm not there. It bothers me a lot that their relationship is private. I know they share children, but I'm sharing those same children with my husband, and don't understand what needs to be private.
Any insight on what's normal regarding the "private" relationship between bio parents not together ?
