I am in love with my best friend’s girlfriend. I’ve had feelings for her from before she got together with my friend, when I found out my friend was attracted to her I swallowed my feelings and helped my friend get with her for the sake of his and her happiness. I assumed that my feelings would eventually disappear. It’s been years and the feeling grows more and more every day. I thought seeing them happy would make me happy, but in reality, I just feel envy, jealousy, regret. I feel as If I am betraying their trust, I feel like a liar every time I am around them. I know I’ll never be able to put myself in between their relationship, so I have to take these feelings to the grave. I feel sick of pretending of being this trustworthy person in front of them, I know if they found out how I feel they would hate me.
