Not sure wat to do?

I have been through the biggest breakup of my life and that even when my dad expired. I was almost dead. Now almost seven yrs have been ped and my ex has got married. My family is searching for my match. Im not happy with this search as im not getting the guy of my choice. There's one guy who knows me from past 8-9 yrs and he knows everything abt me. He still keeps calling me up and he is also in the age of settling down. I know that he likes me and even after saying no to him and speaking rudely wid him because of my earlier experience he still talks to me. I dont understand wat to do. Should i give him one chance . Coz i feel he is my type of person but im insecure. I feel like he is waiting for me only. Wat should i do?
