is it possible....

to love someone and still not trust them? not believe what they say? think they're lieing when they're telling the truth. and yet through all of this still want to stay. still love that person no matter what. is that even acceptable? i feel torn inside. one side of me believes what he says just because he says it, the other side of me doesnt want to be so vulnerable and wants to doubt. i love him. he is the other half of my family. makes me happy when i am sad and loves me back. we could fuss and he is right back to normal and fine 5 minutes later. then there are other times when i feel he is pure evil. mmmm... what to do.
