Baby Mama Drama

I need help my husband’s ex who is the mother of his two oldest children (they are 8/10 our kids are 4/2) told him about a year ago that she’s still in love with him and then even called me to let me know that she was going to do everything to fight to get her family back which is crazy he never married her I’m not going to go into their whole relationship whatever... my question is this;

she has recently started texting him pictures of not just the kids but her and the kids I don’t think it’s appropriate based on her past actions; am I being obnoxious? Please help!
