I would go to a lawyer and get a seperation order then have the locks changed on the house and pack his bags, when he turns up IF he kicks up a stink then call the police.

I was weak and left the marital home as he wouldnt leave, we too had been together fifteen years but had five children whome I took with me. He just kept saying 'I will make you love me again' duh I was past that !

You need the advice of a lawyer.
