What do I do??

Maudeline • Love swimming, shopping, reading books and magazines, I'm a workaholic, I'm stressed on success. Aspiring doctor...
I've been with my boyfriend for 6 years and then comes along a guy from the past we were no more than friends but now I think I'm second guessing my current relationship. He's a great guy, he's nice and caring and we have long conversations. My boyfriend has faults but I always seem to look pass them, now I'm confused... Help please!!!
