His fiancée added me on Facebook? Why?

[Yts]

A few years ago, my ex husband's girlfriend/fiancée saw photos on Facebook of our son's birthday party at my moms house. This girl and I have never met, but he left me for/cheated on me with this girl. By all accounts, she is shy and quiet, but has absolutely no clue that her wonderful fiancee was abusive to me and she seems to not comprehend that if he "cheated with you, he will cheat on you". She commented on the photo that was on his bros page sort of like "when was the party? why wasnt I invited?" 1) she and I have never met and I dont plan to meet her 2) my mom would not allow them over at her house 3) they live over an hour away and he and I do not speak to one another except every few years at state child support meetings/hearings.

My ex's bros wife and I are close and she told me he will not allow his fiancée to visit with her (sister in law) alone. She wants to tell her how he really is and warn him I think but she just says she wants to get to know her. My ex has tried in every way possible to make sure that this does not occur and only sees his family 2x a year or so. Why would she want to add me on FB? I am remarried and moved on.

Crazy that after your husband cheated on you with her (though sounds like she did you a favor by taking him) that she wants to befriend you on Facebook. Only reason I can think of is because of your son, her stepson. If she was sad she didn't' get invited to his party she may want a chance to be invited to future ones.

If you want to be paranoid, maybe it's your ex using her facebook so he can spy on your life. Your description makes me think he was controlling, so seems weird he'd even let his wife have a facebook.

If you message her on facebook and ask her why she wants to be friends on there, I'd be interested in hearing her response.
