I rejected leo man

...And now he won't leave me alone no matter how I explain to him that I dont want him. I really only wanted a fling and I told him this in a very clear manner and he kept insisting that we have relationship...so I cut him off after we had intimate relations that day I ended it and left promptly.
If it matters I am a capricorn.

So I am just curious, cause I dont want this to turn into stalking....what would make you leave someone alone. How can I turn him off and make him forget about me, or at least not pursue me so actively.

I only pursue people that continue to engage me and respond. If they completely ignore me, then I get annoyed, and they'll be lucky to ever hear from me again. I'm not sure if that true for other Leos as well.
