<human>: This guy and I have been super close friends since we were 16, he met this girl a couple months ago and they started dating now. They've been "together" for 2 weeks. I've had a huge crush on him for about a year now, but I've never told him about it because I don't want to ruin our friendship. He hasn't had a girlfriend since I've developed a crush on him, so this is the first time I've had to deal with me liking him and him having a gf. 

Her and I don't get along great, we've met twice now and I was admittedly kind of rude to her, but moreso in a territorial bestfriend way, not a I want to date your bf type way. How do you think I could get him to break up with her? I'd rather not tell him about my feelings for him, so I was thinking of doing something to make her look bad or to persuade him to leave her. I know that probably sounds bad, and I know it would be wrong but I really don't feel comfortable with him dating her. If I tell him I like him, I'm worried that he won't like me back and that would ruin our friendship and make everything awkward. But I also worry if their relationship gets serious and they're like a year into it, then I'll regret not telling him how I felt. I think since their relationship is so short that it's not as bad if I make him leave her as it would be if I did it later on? I only want to tell him if I can like have complete certainty that he'll date me if I tell him. This might be messed up to say but I feel an entitlement to dating him, especially since we've known eachother far longer than he's known this other girl. What would you guys do in this situation? I'm really nervous about acting on it because I feel intimidated by this other girl, I'm not a very confrontational person and I'd be afraid she'd get mad at me if she knew I was trying to get him to leave her?
