Also,(Langy11 again) whats wrong with your son taking his daughter out on the saturday,on their own, before returning her to her mum,so youve your Saturday free? Or getting the bus or the occasional actual taxi rather than treat you like one? Its not you whose run his debts up,its not you whose the cause of his break up,(doesnt matter who,or what is) im sure its not you though) you are the one whose helping him,but now hes taking the mick,put a stop to it now,or hes going to guilt trip you forever,for whatever he wants in life. and why should you have your whole weekends disrupted,while his ex has every weekend child free,to herself to do as she pleases,or put her feet up,etc while you take over? Yes,its your GC,yes,you love to see her,BUT,your not her mum,and none of this is down to you! Stop being guilt tripped,and put your foot down,and help your son make some kind of 'payment arrangements' for debts,then to start saving towards his own place again,even rented,name on housing list,whatever? you dont say if hes working,but if so help him sort it all practically,but tell him its to be a shorter term thing with you,and look towards that.if youre happy to have him long term,tell him it MUST be every other wkend ONLY-and dont give in.Good luck.let us know how you get on.
