A guy I was best friends with for about 6 years.
I never knew he had feelings for me and when I started to get with my current partner years ago, he became very controlling and a down right prick tbh. It all came to a head when he found out I lost my virginity to my partner and he flipped. He grabbed me by the throat and slapped me and called me every name under the sun.
That was about 6 years ago and we haven't spoken since. Can't believe the nerve of him.
