sorry to hear its blown up mate, but you need to get legal advice asap, as i'm sure she will have, or have people in her ear acting as "solicitors", fact is, if she decides not to leave the house if your "time apart" becomes the end of the relationship, it doesnt come down to affording it mate, she can then claim alot of benefits to help her stay now she's "single", plus you have to pay csa PLUS, and here's the biggy, you have to pay half the mortgage until the child is 18 or until she moves out with/meets someone else, at which point it goes to courts or an agreement for percentages, basically mate, be careful, she can have you paying half her way in that house without you even being/living together etc and they pay no attention to your circumstances and whther you can then afford to live elsewhere, a friend of mine is currently in the same boat, and not even allowed to touch any percentage of equity to sort himself out
