MandyMoo I'm so sorry and I understand, but I hope you'll take Smileless's advice and not just turn up unannounced. IF you do, you may find hes too shocked to react, but later gets angry that you caught him unawares.
As time goes on , I have no desire to contact "the source" and I have decided that Christmas is cancelled as far as they are concerned. The door is shut. If in future they want someone to pick at they can go to their (selfish, uncaring, useless and absent) father as HE is the one who deserves the abuse for dishing abuse out and wrecking the family as it was. I wash my hands of them and live in peace.
I did my GC's birthday earlier in the year and got no thanks , just rudeness. I'm done with rudeness and being estranged. My money will be better spent- on myself! Life is short and I plan to do what's good for me from now on.
