Are you afraid in marriage?

I am really afraid of getting marriage.One of the main thing I am facing is that I hate guys much.I had a past relationship and I loved that guy very much .When I heard him dating with many other girls and was really flirting with me I moved away from him .And now he calls me and threatening me that he won't allow me to have marriage.I have given him many cards and gifts and he is blackmaling me for that reason.I don't know what he will be doing after the marriage.I am afraid to get married since this guy is much rich and have nothing to lose.I am not able to tell my parents about his threat since they will come to know about my past relationship.

honestly i have doubts when i got married. it was a fast decision. we've met only a month, then i got pregnant then we decided to marry. til now so far so good. with so many misunderstandings but stil surviving life itself. we have 2 kids, 1 child from my previous relationship.
