I found a girl I liked, I was on the brink of telling her but she basically started going out with someone a week after.
I thought I could get over it, so we became just friends. We became best friends, all the while I just fell in love. I tried every stupid act to try and get her to split up with her boyfriend, subtly, but none of it worked. I tried to spoil their relationship.
Eventually I told her, and we ended up having a sort of relationship behind his back.
I look back and I can't believe how I acted, I was completely selfish to her boyfriend, he did nothing to deserve the way I acted. I ruined it for them in the end, even though they were in love, just because I got tunnel vision and couldn't think of anyone but myself.
