My ex's girlfriend keeps calling our children her step children. As far as I am concerned she is dating him but my our children are nothing really to do with her yet as they have only been together 5 months.
They actually had an affair when my ex and I were married (and I was pregnant) and now, a year later, they are back together again. I will admit I am jealous of their relationship as I am nowhere near ready to move on yet.
I took our children to meet her as she will be in their lives to some extent, and she patted them on the head and introduced herself as their stepmum. I corrected her right away (they aren't even engaged let alone married) She also posts pictures on facebook of them in an album entitled 'My Family'. Which annoys me because they aren't her family, and she shouldn't be posting pictures of my children. I have asked my ex to have a word, but he sees it as harmless and doesn't want to cause friction.
Does anyone have any experience of this? AIBU to not want my children to call someone stepmum after 5 months?
