Hi, after some advice from anyone in the know really. I am a LP with 2 dc's. dd has a good relationship with exh & he sees her overnight once a week. Ds never been acknowledged by his dad.
At the present time I am seemingly stuck in a 2 bed private sector flat. (Hate living here, gets me really horrible & low from time to time) council won't help unless I'm homeless landlord not willing to evict as its too costly. A move to a new private let in my area not financially viable.
I have the chance to move 80 miles to a 3 bed house in a really lovely village. (I'm on outskirts of London now, not a fantastic area). I have friends in the village, next village & nearby town, shall I go for it!!!
I think I'd be a happier person there & dd is very keen on the move. Ds just a baby. Exh (dd's dad) understandably upset although I have said I'll do all I can to enable him to see her as much as possible. Currently I don't drive but I'll learn so he won't have to always drive, & when I can afford it I'll bring her down by train. Am I being selfish, journey is mainly motorway 90 min max in most cases. He is a police officer so gets quite a few weekends off. He has a partner that drives & no other dc's yet. 
Please be kind I am fragile tonight! 
Also is it easy to claim housing benefit in a new county can they ever refuse to pay it??
Thank you.
