I also wanted to mention how it is important for you and your DH to look after yourselves Defeatedmum.
The pain from not seeing your Gc will be there but you will go on. Have a rest and do things for yourselves and each other, You have got through this last phase so see this as something new... .a new chapter. You know the saying... ."before the storm there is a calm" well for me I just want it to be calm,calm, calm
so Iam putting myself and GC first.DD is no longer the captain of my ship!
If you are going Lc with your dd drop her the odd text occasionally just saying something like "Hi dd hope you and gc are well".
Keep it simple. No questions with an expectation of a reply or give too much info about what is happening in your life. That way If she replies great... .but dont wait for it.
You dont say how old your dd is but I know from my experience that dealing with a pwBPD longterm can age us overnight. My dd is only 2o yo but I feel ancient like I have lived 3 lives already!
All the best,
jsf.
