Thoughts.com Blogs - ??confused??

Well i went out to a family dinner tonight. And i was talking to my grandmother. My family is so confusing so i'll try to explain the situation black and white. My mother and father are divoreced. I have two sisters both older than me. My father and my eldest sister are Jehovahs witnesses. My mother and middle sister are not religious. I am neither there or here.
I have always been sided much with my father and sister but i never comitted.
I feel that now i have a boyfriend i am like my mother and my middle sister who has a 3 year old daughter out of wedlock. But i have not had sex nor has my boyfriend of 5 months ever pressured me too.
I am confused that if i continue with my relationship which means the world to me am i betraying my family that i am regarded so highly in. My father, my sister and my grandmother. I was my with my grandmother earlier as i said and she mentioned how blessed she was to have two grand daughters who have steered on the right path. But i have a boyfriend and my father and sisters and grandmother dont know. I am afraid of the out come and what they will think of me. Even though i am still innocent some what.

What is your honest opinion?

thanks.
