Ex is constantly texting our daughter when she’s with me

I’ve got week about custody of my daughter. She’s 10 and since I broke up with her mother we’ve always had 50:50 custody.Issue is that my ex bought our daughter an iPhone and constantly texts her to say she misses her, she loves her, she wishes she could see her, can she please call, where is she etc etcI don’t have a problem with my daughter communicating with her mother, but the constant demand for attention from her mother makes my daughter anxious without her realising why.When she’s with me she’s always saying she misses her mother but other than that is happy. She tells me she doesn’t miss me when she’s with her mother and I think that’s because I’ve always encouraged her not to.My daughter also uses her phone to talk to her friends so the phone isn’t all bad, but what should I do to manage her mother constantly intruding on her life? via /r/Parenting https://ift.tt/2N4B2hy
