I agree with Judi. My best friend has been with someone who dabbled (sometimes heavily) in drugs and there have been many arguments between them about his drug use. He did clean up a lot, for the most part, but there are still times when he’ll do them. And she actually enables him, whether or not that’s how she chooses to see it. Because rather than have him go off somewhere without her, she’ll agree to doing them too, just so she can be there with him. He hasn’t touched any in a while (besides pot, probably) but my best friend is pregnant now so that has something to do with it. The thing is, they were in Alaska a lot of the time, for the past two years, so he was away from temptation. Once he’s back in Portland, I can’t say that I have a lot of faith in him to resist what he was so used to. Especially because he’ll be around a lot of his friends, that are into the same things.
If someone wants to change, it shouldn’t be for circumstantial reasons. It needs to be for them and them alone. Until the day comes that they realize that, I wouldn’t put all of your heart and soul into someone that has an addiction. Definitely don’t stop being friends with the person, but just don’t put your heart on the line. Also because if it doesn’t work out between you two, he’ll be much more likely to abuse substances again – because depression and drug use go hand in hand a lot of the time.
