Help!! How to Evict or get Someone Out of My House!!!?

Hi, Here’s my story. I live in Northern NY. I own my own home, and have been living with my boyfriend for a 1 1/2 year now. I have been asking him to move out pretty regularly for the last 6 months and I have about reached my wits end. Whenever I ask him to leave he tells me that it’s just as much his house as mine and that if he leaves he will take all my stuff with him, and there is nothing I can do about it but take him to court and by then he will have everything!! (I just recently bought all new furniture and a new plasma tv). He has a very bad temper, and throws fits when I ask him to leave. I called the police once and they told me Id have to evict him. I went to city court to get eviction forms but they said they didnt supply them. Mind you he has been unemployment for 5 months and barely give me any money to help with bill’s. Sit’s around all day doing nothing!!! What a prize I got!!! I would appreciate any help you can give me! I dont want him to take all my stuff!!! Thanks!
The house is mine, I bought it way before I met him, my name is on everything. I have reciepts for all my furniture and belongings, which I will get together tonight and put in my safe deposit box. Thanks, Everyone!!!
