My DP's DS (just started seconday school) has made it clear to his Mum that he wants to live with us full time after being dumped with anyone for years and the Mother has agreed to a months trial.
We have everything he needs already as he is here way more than 50%.
We have also wanted this for years as the Mother isn't mentally stable to properly raise a child but she likes to be in control.
How do we make this so it's not a trial run, we want DS here permanently and we know deep down the Mother does too. She's not made for being a Mother but I don't think she's fully let go of my DP still, so it could just be a chance to pick at us and rip him away when she's ready.
Does anyone have advice on how to deal with this in the right way for DS? is offering trial residency showing she's giving up? Weirdly I can't find anything online for this sort of thing..
