i dated a girl in my jr year of high school that was not right for me at all. lots and lots of red flags that i couldn't see at the time. she would show up to hang out with me really fucked up and high almost all of the time. being a little drunk or smoking weed is not a big deal but when you are constantly calling people for percocet and aderall there's a problem. she was full of empty promises and tried to string me along. i finally wised up and stopped calling her.
i heard she had herpes later on. i'm glad we didn't bang. she's been in and out of rehab since, popped out a few muts and married some douche bag.
i regret certain things about relationships or the way i acted during them......not so much the people involved.
