Im in a relationship for 6 years now..?

when i was 18 i developed a strong feeling for my friend - a girl. we've been 'on' for two yrs (i was the guy in our relationship) then i broke up with her bec i realized that i want a normal family life. however, i still love her and feel that i cant live w/o her. we still see each other now though no strings attached, she also feel the same thing abt me. my friends said that im torn between my values and my feelings. i still like guys and want a family of my own; but then i dont know why i love her soooo much. so right now, im just waiting for the guy who will sweep me off my feet. i'll just hope that this time, it's stronger than what i feel for her. am i insane? am i alright? why do i love her this much yet i still hope for a knight in a shining armor?
