Thank you everyone and, in response to legospringqueen and Castleontheisland - I do think that it is LB controlling her but that it is positive that she has reached out to DD2 and her former best friend, although I fear that she may have left it too late. And I worry about her and her isolation and also about the DGC.
Having said that, I still feel angry - about her previous treatment of DH, me, her DGM, her sisters etc. I had a therapy session today with my new therapist who was understanding and is making me feel that it is ok to be angry. I have tried to avoid it, as being angry disturbs my equilibrium, without altering the situation. But if I don't let it out, then it eats away at me and I can see that's not healthy. We also spoke about trust and power in relationships.
In the meantime, and on a more positive note, I went to France a couple of months ago, with a view to putting my house on the market. The first day, I went to lunch to a restaurant which I never usually visit, which has the same name as the 'pet' name I had for DH. I just felt oddly drawn to go in. Just as I was finishing my meal, two men came to sit at the next table, father and son. We got talking, they had come out from England to look for a holiday home for the family. They came to view the chalet and fell in love with it and - touch wood - are now buying it; draft contracts have been drawn up. They went out again over the weekend with the family and seem as keen as ever, speaking of serendipity and the stars being aligned etc. It certainly felt like that to me and I am convinced that DH has been helping behind the scenes 😂!
So, all being well, and given that the notaire is happy that DH's share passes to me under the terms of his will, the property should be sold and the monies transferred back to the UK over the next couple of months. Which would be amazing and one less thing to worry about.
But it also raises new dilemmas - about the terms of my will, who inherits what and should DD1 and DGC inherit at all. I confessed to my therapist that this is the only power I feel I have, but I don't want to abuse it. Also, the DGC are innocent in all this, and what if DD1 needs money for an escape route later. But I really, really don't want LB getting a penny of what DH and I worked for. I know that it won't be my problem, but all these deaths including, most recently, that of my dog, have made me aware of my own mortality and the need to leave my affairs in order.
