IT’S a difficult situation – you can’t babysit him or force him to stay in.

That will cause you to break up anyway because he won’t be happy that you’re monitoring his every move.

You need to decide in your own mind what you are willing to put up with – then stick to it.

If you want to be with him, then all you can say to him is, “I am trusting you, but if I find out that you’ve done it again, I won’t ever be able to trust you and we’re done.”

Then it will be down to him to work out what he values more – taking drugs or his relationship with your.

Make it clear that if he wants to take drugs, then it’s his life to do with what he chooses – but you won’t be by his side.
