Hi the complicated, I agree with m1k3, I was with my exgirly for a year, I thought the same things, her friends even told me I was changing her, BULL**** its all rubbish, the lies get worse, everything gets sooooo much worse. cut your ties, im sooooo sorry to say, but 4 months wasted is better that 1, 2 5 years wasted. It is totally up to them to either hit rock bottom or Die. remeber YOU CANT help, YOU CAN help yourself.
all the best.
