Thank you all for your input, we are having a difficult time ourselves at the moment and so probably are just a tad over sensitive. We do know their other friends and whilst we don't socialise we do swap plants, catch up if we bump into each other so perhaps I should invite them round along with our friends to widen the circle.
Re Christmas, we didn't expect to host this year as we had hoped the family issue had settled down and we have our son and family coming but they sort of invited themselves and we didn't have the heart to say no! Our son is fine with this but perhaps next year we get in first and change the dynamics.
Re the trip, nothing is planned yet so I think we will look again when we are feeling a bit more positive.
well I think that given that they are coming to you for Christmas and did so last year as well, that even though you are not 'In' with their wider circle, it would have been polite of them to ask you to join them at a couple of these outings, not all, as it would perhaps be long standing friends of their own but just to a couple of outings where you could mix a bit more with these people. I would have felt sensitive about it too.
I would test the water myself and next time they say 'Oh Peter and Julie want to try out the garden centre so we're going with them' Jump in and say 'Oh we'll come too, we've always won dered what the garden centre is like, what time are you meeting?' If they don't invite you, then I would say you are busy with your son at Christmas !!!
