Jealousy factor - away from me pls

I hate being in the center of couples. I don't feel comfortable and i don't feel nice and most of all, I hate that feeling!! BO song. NOT that I feel that coz I don't have a bf, it's because it's becoming too fake. Some things i have no idea how to explain it. And to tell, the truth, I can't talk bout this. I don't want to ruin anybody's relationship. I keep it to myself. Just don't make me the "jealousy" factor. I will feel as if i'm being used only and don't feel well.
