Have you been in my place?i am going to marry a man but i don't know if i still love him?

i am about to marry a man, which i do love most even though we quarrels every time. i love him very much. i can't live without him.i think?! that's what i feel before. but now, i have meet a guy who can accept the real me. gives everything to me. loves and cares for me. regardless about my past. he accept me of who i am. i learned to appreciate the love he give. then i fall.. accidentally.. i told my bf about it. that if he had been stopped quarreling with me. i won't fall for another guy. being so fool i still want my bf to come back to me. so i did.. we will still pursue the plans we had. but i can't easily forget this guy who really done good to me. what should i do?
