I do think that no matter how sick I became, I always had a twinge of seeing red flags. But I was very, very good at talking myself out of taking note of them, and dismissing them all together in the name of a good looking, fun guy liking me.
Its easy to silence those twinges when we don't look at them as OUR very important feelings. I don't know why our gut feelings got shoved to the bottom of our priority list...but I know it's not going to happen again. We can learn to really hear what others are saying to us, and to really listen to ourselves and our instincts on what they are saying to us.
That's not to say that people we love won't lie to us (we're all human)....but, I think we can minimize the extent and depth of the lies to us buy picking people around us that don't give us those 'this isn't right' twinges.
