OW putting selfless of her with my daughter on social media

[QwertyQueen]

Says it all really.
STBXH and her have been together 2 years now, divorce going through on Thursday (probably why I am having a very emotional response), but I saw a picture of her taking a selfie with my 4YO daughter, and a pic of her and my STBXH doing a selfie with her too.
It hurts like hell. That was supposed to be my family.
And to put it on social media - fuck.
I want to e-mail her and tell her to take all picture of my children off her accounts. Can I do that?
Or am I over reacting and must just learn to deal with it, that she is part of my kids lives and get over myself?

OP

Thinking of you today. Sounds like it's been a long and tough journey. Shorter term it may also be hard but I feel there is light at the end of the tunnel for you!

To everyone else struggling with things like this, am I the only one who thinks the logical (and sanity saving) step is to come off FB. Honestly I came off as soon things went south with STBXH. Don't miss it one bit. Find myself speaking to the close friends I want to stay in touch with. Quite liberating actually, may not ever go back!
