DP needing advice re. his ex.
DP is non resident parent. DSCs live with ex-wife and stay with DP every other weekend plus a week in school holidays.
This is as per a legal agreement following the divorce as DP is a farmer and works very long hours and can't guarantee being able to have them more, and has to work to be able to support them. He pays properly as per the CSA, but cannot really afford more than this.
Since the divorce, the ex-wife has become seemingly strange in her behaviour. Refusing to get a job when the youngest started school as it was more financially benefical to be on benefits, went from being quite normal looking to being covered in tattoos and piercings and hanging around with an odd crowd (drinks/drugs), doing cheap cash in hand "alt-modelling" i.e. cheap looking topless shots that look like they were taken by some pervy photographer in his living room, and generally refusing to cooperate and communicate with DP. At this point, can I add that DP did not break up the marriage - she had an affair, and he has (totally as far as I can see since I have been with him) been very fair, reasonable and almost too lenient on her when she makes demands on him last minute that he cannot possibly fullfil as he works full time (like an hour's notice that she cannot pick the kids up from school). When it is her weekend off, that is just that - even when one one child went into hospital on her weekend off, she wouldn't change her plans to be there for him).
DP if desperately worried about the kids as he sees her as becoming unstable, but she refuses to communicate with him about the kids. He would love to be resident parent and has offered to be as we live on his family farm, and despite his working hours he has a strong family support network of family also living on the farm. Unfortunately, cannot afford legal battle to try and change the current legal situation, which was the best thing at the time it was arranged.
This week, DP and ex-wife had a meeting at the school regarding one of the kids. Apparantly ex-wife kicked off in front of the head teacher saying that DP never helped/supported her, and that she was exhausted and depressed and couldn't have a life of her own as the kids are with her a majority of the time (yet she's always turned down DP's offers of support as she'd lose her benefits). Headteacher said social services should be contacted as the ex said she wasn't coping. She is claiming DP does nothing to help but she never responds when he offeres to help her. Either that or makes requests on completely unreasonable/impractical timescales.
DP thinks social services being involved is a good thing as it will only serve to sort out what is best for the kids.
What is the likely turnout for this situation? Does anyone have similar experience of being non-resident parent and having an incommunicative ex-RP? Is it likely DP would be awarded the kids? Or does the mother always get the kids regardless of whether she is a "fit" mother? Any advice or experiences appreciated...
