Did you really say that your parents won't allow their own grandchildren to stay overnight?
I did, it's on of the querks in my sitch and you might not understand. They would happily have them if I'm not there, but not while I'm there for 2 reasons. 1) The first letter I recieved from my STBX sols was her (and her solicitor agreeing which I cannot believe) that I should leave the house and go live with my parents who's house was also big enough for me to have the kids stay over. WTF - My STBX suggesting it yes, but a sols writing it ??? This is nothing to do with my parents and not their responsibility, they don't even have to have me there. 2) If I did that even a few times, it would start a precedent.
Sorry, you may not fully grasp that, but having spoken to my own solicitors (2 different ones in fact) they agree her sols should not of even put that in writing as it is no responsibility of my parents.
Trust me, I feel really bad about not having somewhere for my boys to stay but rental prices here are obscene and even a 1 bed would cost approx 1/3 of my wages, I'm paying mortgage on house which is approx 1/3 of my wages so I could do it, but would be living on pittance and have no extra money for any sort of social life and I reckon I would crack up !!!
