Hi anna, I'm in a similar boat, firstly get a parental resposability order giving him equal rights, secondly seek legal advice for access to the child, dads have rights too. look into the property details if it's a shared mortgage they have, then again seek legal advice, if it's in his name then there is nothing to stop him from selling the property and her having to find somewhere else just do it nicely by giving her say 6 months notice to vacate the property first. Try not to row, i know it's hard but it's just more strain on you relationship, you really should recommence the csa payments as much as it might apin you to do so, it's not for her it's for the little one (be the bigger person). hope it all works out for you. x
