@AcrossthePond55 and everyone who posted yesterday, thank you so much.
The kindness here made me cry - there are so many good people out there, you ladies are proof of that , it gave me hope yesterday.
Just couldn't reply yesterday as had a mini meltdown with all the crying and then felt sick. Still not okay today but better.
Dsis called up last night, apologised, cried and insisted I come to her town not Dcousin's. Don't know why that was not the initial response and what happened but I accepted the apology but said I would stick to near my uni friend if moving, it would still be a lot closer either ways than now.
H knew about what went on - as my DM also called a few times as I was crying the whole day like literally someone had died.
As you all predicted, I don't think now that he could have meant it 100pc seriously about leaving to retire in India in August near his dad - he seemed completely shocked that I was making real plans to move, he appeared embarrassed that I was telling everyone he had consistently been saying he was leaving because of DS not getting all As, his own constant grumpiness, his depression and moods etc.
He took DS out for a burger in the evening and told him 'I am going to try my best to never argue with your mother again, I promise...I will just keep silent and talk to a minimum to keep the family peace but won't be grumpy...' yada yada....DS never told me this but H texted it to me re their convo.
I know my plan changes again and again since Nov, but now my plan is to go ahead and move over the summer to near his Dcousin in BKshire, or my friend in Herts - just to give me and DS our fresh start, if he comes along with us I think either ways - things will improve - with all family around, he will either have to improve his behaviours and we can see where we go from there to at least amicably separated under the same roof for two more years etc - or having family around, gives us the strength to separate if that is what we decide to do once we are there. I just think whatever is going to happen, it will only once family is close by - his aunt whom he is quite close to visits his Dcousin regularly and I just feel all of the 'village elders' presence will provide traction for progress whatever happens, we won't stay stuck in this rut that just feels like a slow spiral downward.
Thank you all for your advice - I know this is not the bold courageous sweeping move many of you hoped to see , but I am moving this along in a slower subtler way to improve quality of life for me and my DS in the only way I am capable of I suppose. I just can't help but think an abrupt separation here will allow any rumors to fuel there as to how things fell apart - it will be good for the family to see how he is and understand my situation before I leave - for a bit at least. He is good at charming facade from a distance for the past 18-20 years now.
Thanks again to all those who followed this for almost a month now...... can't find the words to express my gratitude, I know you may not see progress but I do not think I would even have gotten to this place from where I was three weeks ago without you all......
