So i'm separated with a 4 year old daughter and have been for nearly 2 years. we were never married but were together for 6 years and separated due to me discovering an affair my partner was having.
After dealing with the emotional fall out with the help of friends and family I put together a parenting plan, trying to make it as fair as possible. The plan split the time 50/50 and alternated weekends with mention for Easter and Christmas.
There was a section for my daughter's Birthday saying that we could both be there and that as most birthdays will fall on a weekday we will just let the weekend fall where it may, but last year we split the weekend a day each and it worked really well. It also came to light that they were now with the person they had the affair with.
It is still a few months from my daughter's birthday and I've started organising the party. I messaged my ex-partner and asked if they would like to come with their parents, who I used to get on well with, and even the person they had the affair with so we could try and rebuild some bridges for our daughter's sake. Just to be clear there is no vain hope that we'll get back together, time apart has made me realise how selfish they truly were.
I get the reply back stating "no it's my weekend", I was somewhat taken aback ask if they were joking but the only response was that it was their weekend and that I they would be collecting our daughter as usual that weekend. I've messaged a couple of times to ask that we talk and come to some sort of comprimise but I am met with the same few words, it feels like talking to a wall. Am I being unreasonable?
