Hiya, first let me say that it sounds like you are doing a great job so so dont let your ex make you think otherwise!! As for the CSA I think it would be wise for you to give them a ring for some info, they wont do anything unless you tell them to but if you explain to them what your ex has said then they will tell you if its true or not. I also get ??200 from my ex (who's only seen his son twice since he was born...great dad eh??), I too havent contacted the CSA because the way I see it Im getting regular money off him if nothing else but I would'nt think twice about going thru CSA if he ever stared to get funny about it. As for letting your son stop at your mums house, that is YOUR choice..NOT his. If you feel ok with the dogs and confident that he will be safe then go for it...a rested mum is a happy mum (cheesy but true!!), just maybe have a talk with your mam and stepdad and ask where the dogs will go and if your son will not be in a room alone with them. Just remember that your are your sons sole provider and your word is final...reminde the absent dad that if he wants a say in his sons life then he needs to be a dad and not pick and choose when it suits him. Hope it doesnt sound like I hate all men or all absent dads for that matter, some are really good dads, its just I get so mad that they can walk away and play at dads from the sideline. Hope it works out for you.
