well, i want to go ahead and say that i have to agree with birch. ive been dating a man for over a year who used to be known as part of a toxic trio and i personally have done mj once about 7 yrs ago, but am completely drug free since then.
my SO decided before we ever met to quit drugs bc they were taking him nowhere fast and if he had an accident at work, they would throw him out of that place real quick. he has flat out told me that if i was ever to try drugs out he would kick me to the curb bc the only thing i would be doing is ensuring a jail sentance for both of us.
dude, the only thing i can say is get out, and get out now. not wanting to sound like a health forum or anything, but shes too far along to have an abortion and the kid is going to be screwed up royally if its not already dead so cut ur losses.
a lot of the time people stay with someone out of feelings of obligation which sounds like what ur doing, which dont get me wrong is commendable, but ur just a kid and need to work on getting ur own life together bc trust me all she is going to do if she really is doped out and has had all kinds of traumatic things done to her, is take you down with her.
i recently saw a movie i would def. recommend, its called the basketball diaries. def. gives a whole new perspective to what people do to themselves and how low they have to go before they pick themselves up.
