Am I engaged with the right person ?

I was born in the 25th of July 1971. I was engaged with a man born in October 25, 1973, two weeks after knowing him. Everything was like a dream and we felt in love from the first sight. Then two weeks after our engagement, he has changed and never stopped quarrelling with me. He is very conservative and jealous. We already fixed our official marriage to the 14th of this November. Actually I feel myself sad, anxious and not secure about my future life with him. I don’t know if I still love him or not. In fact we don’t spent a hole day without quarrelling. Each time I want to cut with him, he begs me to forgive him and give him a second chance. I doubt if he’s going to change one day. Should I stop with this person or he’s really the right person for me?
