I am giving him money but he stil wants to leave me

I’ve been knowing this guy I’m seeing for about ten years. We meet when we were in secondary school. We always liked each other and messed around while we were in school. So, after we graduated we both went to different uni. So, as time goes by, we run into each other again. So we immediately hit it off. He was so sweet and interested in my life. We just started talking and catching, getting to know each all over again. Then he told me that he need some help moving and he was two hundred dollars short, so I helped him. So, after a while he began asking me for money and lots of it. He has a job, but always wants to spend my money.

Then I asked him since we’ve been talking for about a year why won’t he friend me, and he tells me that he’s not ready for a relationship. Then he tells me the only way he will friend me is if I give him a certain amount of money. He told me that if I gave him that then it proves that I really love him and i am down for him. So, I gave it to him and then he started treating me worse than he already was. Then I told him that I couldn’t give any more money. Then threatened me by saying if I don’t give it to him then he won’t ever talk to me again. Then he tells me that he can find another girl who will do what I won’t. Then he only calls me if he wants money, but tells me that he loves me and wants to marry me. I don’t know what to do, but I love this guy. I want to know is he just using me or what? I really need some advice. – I’m So Lost I Need To Be Found
