I have a crush on my co-worker going on 6 months. I think he have an idea that I like him but neither one of us ever push the issue. I want to let him know how I feel about him but am too shy to go to him and let him know. Is there another way I can do this? In other words, let him know how I feel?

Are you kidding me?! You also posted a question that you have a crush on your training instructor! So which is it or co-worker or instructor? Get your question strait!
