Trying to be as brief as possible - DH has a defined contact order. This weekend we should have DSS (9) overnight. We have plans to go camping with friends and our 2 DC's. However, ex is very anti-contact and often makes holiday contact, in fact any kind of communication, as difficult as she can. Often she makes DSS the go-between.
So DSS says his Mum's family are having a party this weekend and he wants to go. DH and I talk about it, agree that it is what he wants then he should be able to, that DH will ask for the contact to be another weekend or half-term. On the way home, DSS asks if we'll get our money back for the campsite. DH says we won't need to, as we'll still be going. DSS seems upset by this, so DH says there'll be lots of other times when we can all go together.
When they get to ex's house, DH asks about the weekend, ex says yeah, they're having a get together, nothing special, can he pick up DSS at 7pm? DH says afraid not, we're going off camping, suggests a swap. DSS then pipes up - no he wants to go camping. Ex gets in a flap about how he can't possibly miss the party etc ect.
DH leaves, the whole thing is unresolved. So is DSS playing his mum and dad off each other? Not sure what to do now.
