I left an abusive partner, my ex was terrible and like you he tried to make me lose all my friends, I was fortunate enough that they stuck around despite him threatening them and putting one of them in hospital...I was in a council property though (in my name only) which made it a bit easier, the council was well aware of what was going on and agreed that some distance had to be put between us, so they offered me somewhere else to live...he went to work and I packed my things and was gone....it was the best thing I ever did, I will never forget my 1st night in my new place, it was lovely and peaceful and I kept saying to myself.....I cant believe I done it! I had nothing really, but I didnt care, and have built my life up since...you have to leave him, its no good, you have to go through a bit more turmoil in order to find your happiness, good luck x
