searching for guidance

I have fallen in love with a muslim however complications have come about with our contrasting religion as I have been brought up in a Catholic family. Growing up I believed in Jesus and the stories told in the Bible, however I never understood how it could be that we could go about our life and live by this book but still sin and go to church on a Sunday asking for forgiveness and feel that it will be provided that easily. The person I have fallen for has told me of his religion and why he believes in it so strongly. He went on to tell how his book (the Quran) has answers for everything that happens in life and how his god has stated life to be lived. I have slowly started reading this book although have some difficulty in understanding some of it and feel that it is opening up my eyes to things that I never saw before or took into consideration. I'm starting to question the religion that I have known for most of my life however do not feel ready to take on this new found religion as I am have yet to learn all about it. I dont know how my family would react to my query however I feel that if they see that it brings me closer to god then they will be happy and look on to see why it is that I have done this. Wish me luck on my journey
