Good for you OP, lovely to read of a woman standing up for herself, finally.
I'm with the women who read these threads and thank god they are single, rather than a life where they are disrespected and taken advantage of.
Of all the people in these children's lives its a step parent that is handed the responsibility to look after them whilst juggling wfh.
OP, glad to hear the house is yours pre marriage, he moved in with you to your home...yea it figures.
Protect yourself.
Oh and to the remarks about feeling obligated to allow months of access via your garden to new neighbours renovating a house, absolutely no obligation.
That's what cranes are for.
A house a couple of minutes from me without sufficient side access used a crane.
It is something that would have to be factored into the cost of renovation.
In a similar situation there is no way that I would feel obligated to open my garden to months of builders coming and going over a garden that we have spent 20 years tending.
