Thank you all so much for the range of advice.
Too many questions to answer them all directly.
The priority in this is DGS, a child aged 6.
I can certainly see that DiL does not have to include us, even if an arrangement was that we would travel to DGS. In the past, we have met half way to eat and do something together, us DiL and DGS. ( park, theatre, zoo etc).
As DiL wants us to end all contact ( informed by WhatsApp group) following gifts sent at Christmas as normal. We sadly, have no choice. There hasn't been any fall out leading to this, we've continued with the pattern of gift giving throughout. We are more than happy to see DGS more if DiL was also happy for this to happen.
Time passes quickly. As a young adult DGS will be able to make his own choices. We will be there for him should he wish that to be the case and we will be able to show that we cared so much for him.
I already have photos of all gifts sent. The parental alienation and court decision that the child hadn't seen his DF is that it us not in DGS’s best interest to rebuild contact given the gap created by DiL frustrating contact. This was always going to play out to us too.
Our DS should have planned his life better after his marriage break up. We advised he focus on contact with his DS, supported him with a deposit for a rented flat so that he could do that. Offer stability and routine. Starting another relationship hasn't helped this situation, though of course DiL did the same in what was the family home (now sold).
DiL and I had a really good relationship, we sometimes met with our DGS, she would drive to my work and we'd go out from there.
Just a complete mess, leaving a young child with only half of his family.
I haven't posted about this prior. I can see from other PP’s that we are not the only ones going through this.
I see through my work the impact of parental MH and instability on children. How children feel about themselves, internalising that the people they loved, seemingly don't love them anymore, that they are no longer in their lives. So sad that this I happening in my family too. The usual grief is tangible, just like the ending of any relationship.
We will lodge information with our family solicitor. We will save all cards, and money. We will write to DiL ( WhatsApp app now blocked) and let her know that this is the case. Better to be clear and open. We will reiterate that we love our DGS and will continue to do so. He will always be part of our family, missed by us, aunts, uncles, cousins and his half sibling.
We will also include some medical history, linked to the male line.
We have one open Facebook post, sharing a time when we did see our DGS. We will repost this every year on his birthday, so that in time DGS will be able to see these. He carries our family name, of course, so it will be easy to find.
I would really like to do more ‘in his name’, ( without making a big deal) something useful. DS has contact with DGS school.
How would it be perceived if we were to buy something for the school twice a year - birthday and Christmas, something that can be used by other children now?
Or perhaps a donation/gift to a charity? Details could be included in the information the solicitor holds.
Any other creative suggestions welcome, we feel quite useless and disposed of. Some good to come from this would be a much more positive resolution.
