Should I ask her why she did that?

I left my husband back in August. It was an over reaction to a situation that I’m no longer sad or regretful about.

Soon after me leaving, my husband got in touch with an ex and they started dating. He flew her up to the state that he’s in and had to fly her back to her home state a week later because apparently she’s “crazy”.

I thought that he was just saying that because he played with her emotions and she reacted, but come to find out this girl stole pictures of my son that I left behind and is using it to reel my ex husband back in. She also added my mom on Facebook... that’s so weird to me. There’s a couple of other things she’s done that’s super weird and I don’t know how to feel or react to the situation lol.

I have no plans on getting back with my ex but we are cool. She messaged me on Fb last week and I haven’t responded but I feel compelled to ask her why she stole our personal photos and why she added my mom on Fb. Should I ask her? Lol

Oh and she claims to see my sons name everywhere now that she and my ex are no longer on good terms. Like girl... what in the world.
