My girlfriend wants me to be christian, will this hurt us?

Okay, my family is catholic, i was bapized catholic when i was a baby but never went to chruch at catholic or at a catholic chruch, I dont believe in praising and praying to "Mary" I pray to god, jesus christ, but the thing is i dont enjoy church at all, i go with my girlfriend when she goes, but i usually dont want to but i just go to make her happy.... she dont like that...idk what to do, i dont want her to end up leaving me because i dont wanna be christian, idk its not that i dont want to be, its that i wasnt raised christian or catholic, i do believe in god...? idk, its so confusing, she doesnt want to rush me but then it seems like she wants to rush me. But i want to try, but what the heck can i do!? Someone plz help!
