Am I A Jealous or Greedy Roommate??

I am a student of a university, ain’t disclosing my identity nor that of my school. I am in the hostel in school and I happen to have two boyfriends. Don’t look at me with that eye, I am not what you think. I definitely can’t love them both equally. Enough of talking about this.
This reason for sending this is that my roommate has this boyfriend. I must say, he is the man of my dreams: tall, not too dark, not slim/fat, has the abs… Please don’t me make obsessed again. The thing is that I wish I knew him before her despite being the one who introduced them to each other. But to face the fact, I am better than her in terms of beauty, assets, height, just think of it. Am practically any guys dream.
The issue is that I have or should I say had a crush for him since I have seen him. I have been struggling not to make a move at him but am finding it hard to do now. I accidentally made a statement that implied another meaning to him in front of my roommate. I can’t cut myself from him because my friends are his friends also. I dunno what to do about this whole issue and I cannot just let the ‘man of my dreams’ walk away with another girl. Please I dunno what I should do…
