Studying Islam and believing..?

Lately I've become really curious with the faith of Islam since my boyfriend is a Muslim. I've always heard bad things about Islam ever since 9/11 but my boyfriend started telling me true facts about his religion that got me interested in actually studying it. Without him asking me to I went on my own, bought myself a Qur'an and started reading it non-stop. For some reason I couldn't put down the book because I found the religion so interesting and peaceful and started believing it more that I do in my own faith. I pray to God to lead me to the right path because I really want to do the right thing and worship God but I really worry that my intentions could be wrong. I'm terrified that I'll be one of the "fake" believers. But maybe its because I'm afraid of what my Christian family will think if I do want to convert somewhere down the road...Is there anything I can do to because a true believer and not a false one....? Is it bad that I still pray the way a Christian does for God to guide me even though Islam is the faith I'm interested in...Please help..
