I want to stop falling in love. How do I do it? ........ So many questions. Read and answer. Tnx.?

Do I have a weak heart? Or am I emotionaly weak? Why do I fall in love with all guy (I mean handsome ones) and each time I fall,it's always with the wrong ones that all they need is sex. They al disapear when I told them I'm nt ready for sex leavin my heart broken. I'm 18. The last guy I thought loves me rapes me because I refused to make love. Now I want to stop fallin in love and i want guys to stop comin to me. How do I do this? And how do i really know the right person when I will be ready to love again? Thanks.
