My friend (S) has a partner (T) who used to be a heavy drug user. When S and T started dating, T almost stopped doing drugs altogether. S and T have now been together 3 years, and T will have the rare cannabis joint with certain friends, maybe once every couple of months.
S is raging because the other night T went out with the intent of not drinking and didn't come home till 9am. If transpired he had taken Ketamin at a friend's house.
T was remorseful the next day and said it was a one off and that it will not happen again.
S is considering ending the relationship.
Should she? Who is being unreasonable?
For my part - her friend - I have said if he has consistently shown to her that he has actually changed his lifestyle and drug habits and that this genuinely is the first time this has happened, she should let it go on this occasion. I myself know nothing about drugs though and now am second guessing the advice I gave her.
