[Solved] Tricky Dilema - unsure what to do?

Hello and thank you for being here.
The situation is this: In 2007 my ex-wife abducted our daughter saying that she'd not be allowed to return to her home unless I agreed to let her (then) b/friend have Child Benefit. After six weeks I had no choice but to take her to court. It was a heart wrenching time. It also cost me most of my savings, over £4k for something that she did. She got rollocked by thge Judge and also had to pay. When settling times the Judge ordered "Status Quo" (equal time), which I was happy with but she played up and didn't want to see her so much; the papers show this.

Since then, she has persuaded a child minder to make false allegations against me a year later; which obviously put me through [censored] and nearly killed me. However, Social Services and Co. had no qualms about her being with me still and things eventually settled down. Working hard on visits I eventually got stays with her mum to the Status Quo. However, I still have Residence Order status. I know she lies about everything and twist events around and even does this "spitefully" in front of my baby girl.

My youngest is almost 13 now and says she wants to go live with her mum. I know her mum has been prepping her and grooming her so that she gets her way, and that she lies about past situations too. It's now got to the point where my ex, now 41, has to give up fitness training as she's knackered her body. She wants "daughter" to go live with her and has asked me if that's going to happen. Since there was an agreement previously about Maintenance, I have not claimed from her. However, being in receipt of CB and CTCredit I have helped her with anything from £10 to £20 per week or more, often giving her extra for clothes, holidays and so on with sums of £50 to £200.

Daughter has now become unsettled at her scholl and mum says they have lots of chats. I'm concerned about this as she said at first that she didn't want to move school. Ex-wife said last week that she'd take daughter to school but daughter would have to get two buses back. This week she says that she will not take her to school - leaving longer journeys and tiring days only option for my girl. Ex-wife has also been keeping her off school on the premise that she's tired or unhappy at that school; this has now reached a critical point and I think that daughter uses this so that she does not have to face things. Ex-wife seems as though she's now set on changing her school and overrides me on this as she's "taken control" of daughter and has persuaded her to side with her and that I'm wrong, etc,. I'm worried because the school she seems set on is worse for bullying and repuattion than the one she's at now!

Finally I'm worried that if I allow my daughter to go live with her (which is her current choice, however it was made) that my ex-wife will not only want the CB and CTC, which I have no problems with, but may also try to claim Maintenance from me: I am now 66, on my basic pension and just getting a little help from part-time self-employment. This would effectively cripple me. She has already cost me all of my life savings, and I know that money is her driving force. No matter what she says, she cares more about the money than her daughter! She lost her first child after going into prison for manslaughter when she was in her late teens, he finding out what she wa slike "dumped" his mum and went to live far away.

I still have the Residence Order, which for my daughter's safety or back up I shall not relenquish, but please advise me as to where I stand and what i can or should do as I'm worried that things will go from bad to worse.
