my ex partner has our three children living with her. Despite many years of requesting regular and timely communication around sports days, illnesses, issues at school, successes at school - all the normal things that a parent would be interested in - she is still unable to keep me up to date. I find out things from speaking to the children, or she tells me late or doesn't tell me at all. I appreciate no one remembers everything but she has admitted not doing this as well as she could and apologised in the past but we always end up with me feeling even more excluded than a separated parent normally would be anyway. Is there anything I can do to get her to improve the communication in an official capacity?
