I need help.....

Ok, here's the situation, I'm 27 years old and I have a major crush on my co-worker. Well, I'm not going to even say a crush, I like her, a lot. But of course there's a major obstacle between me and the woman of my dreams( that was childish, I know). She has a boyfriend. Now usually I won't interfere with a happy couple, but like a shark in the water I sense a wounded fish(Ok, that was a super bad example, let's just say I sense a disturbance in the force). Lately I've been hearing nothing but bad things about her dude. Mind you, I haven't been prying into the relationship, this is information that she keeps giving me. And nope, I haven't been hating on the guy or saying anything bad. I do say nothing, I just listen. I'm not saying that the guy is a bad guy, but I do since that he is taking her for granted. What's that saying, "One man's trash is another man's treasure." Surely he's forgotten he has a treasure chest of gold!

I mean we hangout together and have fun; which has been making me think, "How come I got so much access to her?" Where is her dude? It's not like I'm doing anything spectacular, I'm just doing small things that friends do. I notice small things like when she gets her nails done and I compliment her on it. Small things that he should be doing. Truthfully I don't know what's going on, and I don't know if she even has a slight idea that I like her. Hell, I might be knee deep in the friendship ZONE! I'm just letting things unfold without making things weird or uncomfortable. Again I refuse to hate on her guy because he might be a good guy that has just gotten complacent.

I'm interested to here what everyone thinks. I'm interested to know if anyone else has been in my situation. I don't want to ruin our friendship and I really don't want things to be weird at work, but I also don't want to miss out. I feel I deserve a great woman like her. WHAT THE HELL SHOULD I DO?
