Advice needed

I don’t know if anyone can help or if there’s anything that can be done but I just need to vent. I have a 2.5 year old daughter who I share custody with my ex for the past 2 years. He has awful communication and constantly break boundaries I set. Long list but things the include changes residences without telling me so I didn’t know where my child was staying, introducing partners without telling me (we verbally agreed to be courteous to each other), moving a partner and her child into his home without mentioning it, most recently was going to take my child out of the city without telling me (illegal where I’m from), just things like that where communication would’ve been appreciated, I have literally begged just to be informed on things that will affect my daughter.

The latest which I feel some type of way about - him and his partner are having a baby. My daughter for the past few days has been saying “I’m getting a brother” “me and dad feel the baby kicking” and lots of little things, she’s gone on enough about it to know it’s not all made up. Am I not just deserved the decency of a heads up, especially if she’s presumably she’s 5 months along and they’ve been hyping my daughter up about it? I’m just so sick of being the last to know things that will/do affect my daughter. I’m at a point of frustration and yeah it is also kind of shit to hear half of the stuff through my 2 year old as if it’s okay for her to be the messenger. Idk, isn’t it just common decency and respect to talk to each other about life and living changes that will ultimately affect my child???
