You will be ok.
I threw my ex out, after 22 years of marriage and four kids two years ago. A year before we split he told me he no longer loved me, but I thought that we could still make it work. When he told me again, a year later that he still no longer loved me, I fell apart, and posted on here for advice. (I was 'Saffysmum'). The advice I got was amazing, and the support helped me negotiate my way out of the nightmare. I started to feel better once I took control, and threw him out. I got a little dignity back along with the control. You cannot, for the sake of your sanity, live with this man for longer than you have to. Please after the bank holiday, get to a solicitor, or even CAB, who will point you in the right direction of a solicitor, whilst giving you basic advice.
You must not, under any circumstances, move out of the family home. If he can't buy you out, then the house could be sold and split 50/50. Or if you could get benefits and manage the mortgage, you might be ok to stay in it (I was, thanks to a brilliant solicitor). He is the one who wants out of the marriage, so let him leave. ASAP. Let him stay on a friend's sofa - go to his family, anywhere. But you must stay put, get legal advice, and lean on us to guide you through it. Day at a time, hour at a time if need be - but you can do this - so many of us have been through it, and it stinks, but believe me, nothing is worse than living with a cold, detached, emotional-less bastard. If I have any regrets, it's that I didn't chuck mine out the first time he told me he no longer loved me. Good luck xx
