Depressed and Confused

I know I must sound crazy, but here goes. I have been in and it of therapy for several years now. Recently, there had been a lot of stress going on in my life. My fience's wife, soon to be ex wife has just started coming back around to see her children which she had not seem in almost 3 years and she is starting major trouble. She's stalking us and threatening us. We have contacted the police many times for nothing to happen. My fience had been very distant. Usually he talks more or at least let's me talk to him without fussing. Now it's like every time I try to talk to him he says in fussing. I'm a stay at home mom and most the time for the last year is like I feel line he don't appreciate me at all. But, there are times when he knows that he is taking me for granted. Even though I know in not being appreciated I have grown accustom to my little life and have been remotely happy. Well she started coming back around and he's acting more distant and treating me like I don't exist most the time. My depression had really kicked into high gear. I know that most people would tell me to leave him but I love him and I'm not going to leave him or my children. Like I said I have grown accustom to my life. I just don't want to feel so alone. I really don't have many friends and no one to talk to. But I have started talking to, however not often, to an old friend of mine. The relationship been the friend and I used to be more than friends and so I do not know if me talking to him is inappropriate or not. I honestly just don't know what to do. I want my life back and I want to not feel like I do anymore.
