So this evening I received a phone from call from LOs dad telling me that my LO is too tired to go to his gymnastics class, I tell him he needs to go the class has been paid for already. At this point the dad has already said he will 'try' to take him if he has enough for a taxi (A walkable distance), so I'm already thinking he's trying to get out of taking him. Get a text 10 minutes later "why do i have him if you're gonna book him into all these things without asking me? It's not really fair is it? So i'm now just your baby-sitter and not his dad?". Then the phone call, I straight away say, "do you just want me to take him I can come now" (in an obviously exasperated tone). But no he flies off on one shouting at me that I don't have the right to organise anything on the days when he has his son that he is going to the solicitor tomorrow (we don't have any court orders in place) to make sure I can't make him do anything he doesn't organise with his son. Bearing in mind he works shifts on a 6 week rota, meaning that his days off are different every week, so this week he was meant to have him on the weekend, but they changed his rota so he had him tonight instead, after I juggled my schedule around to suit him. My retaliation was that he can't possibly make me not book any after school activities for my son because it might clash with the one day a month that he has to take him to it!! There were more angry tones in that bit than I'm able to demonstrate typing. I go out of my way to organise activities for my son so that he can have a great, fun, well rounded childhood and not feel like he's missed out because we are 'poor'. I don't get child maintenance from his dad and haven't for 5 years, so yes it annoys me when I've paid for something that he enjoys and his father can't be bothered to take him because he might have to walk. Am I being unreasonable?
