Ok so first time poster here & apologise if this is long as think it's important I try and summarise everything.
I've been with my partner 4 years, lived together 2.5 and he has a DD (7) whom he has every other weekend for 4 nights. At the start of our relationship communication with his ex was at breaking point. He would receive multiple messages a day sometimes totally unrelated to their DD, phone calls if he didn't reply to her message within 30 minutes, stating things like 'I'm the mother of your child and you will pick up the phone to me'. He had tried numerous times politely asking her to only message if really important about their shared daughter and he began ignoring messages. In the end she took this to mediation (not entirely sure reasons as to why) but it was basically agreed that they only communicate via email moving forwards, unless an emergency which warrants a phone call and a contact schedule was officially agreed in writing. Partner was really happy with the outcome and the last 2 years have been pretty much smooth sailing. She did also meet someone fairly soon after so not sure if this had anything to do with it too (I imagine so!). His daughter would come round and say stuff like she had been to the doctors for this & that and had her eyes tested etc etc and my partner was never told about this. He didn't say anything at the time as tbh I don't think he wanted to rock the boat. I do feel that she was almost doing this deliberately as if to say 'you don't want contact therefore you won't have any'. Who knows really...
Anyways, roll on last week and he received an email from his ex a few hours prior to pick up, stating that pick up would have to be from her house & not school as normal as DD was unwell. At the pick up, she handed him some medication for DD and said that she had been at the walk-in centre 4 days ago as she had a very high temp. This was obviously news to my partner as he wasn't aware of any of this or the fact she had been off school all week.
My partner is obviously not happy with this, but equally doesn't know what to do? Does one go back to mediation to get this sorted? What do people here do about medical issues & communicating? Thank you!
