I split up with ex H about 2.5 years ago, we have 2 children aged 8 and 11 and each have them 50% of the time. We have recently changed our contact schedule which was previously alternate days, and is now every other weekend and 2 nights in a row each during the week. During negotiations over the new schedule I suggested the 2:2:5:5 pattern but ex didn't want to be away from the children for 5 nights in a row, but he did suggest that we could stay in touch with the children during those longer stretches by phone or playing together online on the xbox (I don't play but he seems to be on there a lot of the time). I agreed that would work but then we didn't choose that contact schedule anyway so phone calls/xbox games wouldn't be needed.
In the last couple of weeks whenever the children are on the xbox at my house (which is not much of the time) he seems to be online and they start chatting or playing a game together. I let it go when it was at the weekend, but this also happened one evening after school, which I wasn't happy about. I can't say anything to the children or ask them not to talk to him or play together when they see him online, but what can I do? I'm pretty sure that he wouldn't be happy if I called the children for a 30 minute chat after school but it's basically the same thing.
Am I over reacting, it just feels like a huge intrusion on my time with the children. Does anyone else have experience of this kind of thing?
