Hi all please excuse me if a ramble on and this doesnt make much sense but there is so much to explain.Ive been an emotional wreck over this and dont know what else to do.

Ok first off as some of you may know my BF and i have legal custody of his 2 sons aged 4 and 8 and have done for 2 and a half years now.
They were neglected severely and were discovered in the most appalling conditions imaginable-to give an example which is recorded.....the youngest was found to be drinking from a toilet as they were left on their own for most days.Anyway they were placed with me and my BF and she wasn't prosecuted as they were then deemed safe.
So in theory have brought them up as my own and love them just as much as they were. They still see their mum quite often and this week they have had the whole week with her as they are off school etc.
Anyway i had a knock on the door yesterday and it was 2 police officers from a childrens unit a man and a woman. They were really nice to me and explained that i needed to be arrested on alleged assault charges on the boys from a date in the previous week in an incident where i placed them on the naughty step after they were messing about.In other words their mum has made more of this situation and has made a complaint to social services who even after the neglect wanted to place them back with her!!
So i had to go to the police station and was given my rights etc,had to get searched and all the other routine things they do,fingerprints,dna,mugshot,made to feel like a criminal etc etc
I got questioned on tape etc and at the end the officers said there is no further action and stated that they think it is all fabricated and a waste of their time.
Anyway we are supposed to get the boys back on sunday but now their mum has said that she is not giving them back etc and we phoned the boys earlier and it seems like she is putting words into their heads and coaching them as they didnt want to talk to their dad which is breaking our hearts as we know that they must be going through some severe mental/psychological things right now.
Their mum is desperate to get them back as it would give her more money as she gets income support due to depression etc......we do not gain financially at all(benefits/tax credits)by having them here.
Anyway social services are being their useless self again and not communicating with the police that there is no case to investigate etc and wont help us in any way.We now have to wait until monday when our solicitor gets on the case. Next week we also know that she will be applying for an interim residence order! if she gets that we may not get them back for months......but then there is no case to investigate for her to have the right to that.
I hope this makes sense. I have been wasted the last couple of days over this and cant stop crying/sobbing/getting angry. Last night i had some pains under my bump which were quite regular which i hadn't had before and all last night and this morning i hadn't felt any movement so went to the hospital today for 3 hours to be monitored and LO's heartbeat is fine thankfully but seriously......how much more can i take!!
Does anyone else have experience of the crap social service system we have here, they have failed us time and time again
This is just a nutshell of everything but just wanted to vent.
