Hi, I use to be an alcoholic and cocaine user for more than 20 years and let me tell you what I say to my clients who’s been in your situation.
First of all, by reading what you wrote, I can clearly see that he’s probably lying to you. Most of the time, an addict has a victim mentality and tends to blame others for what’s happening in their life.
When you have an addiction like cocaine or alcohol, you’ll try to evade any questions about that subject by coming up with excuses that don’t make sense.
Like the one where he told you that he had erased the text messages because his friend was asking him drug dealer’s numbers, and he knew you wouldn’t like it.
If an addict can’t think of an excuse right away, storming out is a suitable defense mechanism.
When addiction takes over, an addict will do anything to feed his addiction. Unfortunately, that means lying to the one closest to you. His addiction has become bigger than him, and the worst part is, he probably thinks he has it under control or doesn’t have a problem at all.
And take it from me, an ex-addict, when you get sober, you don’t hang out with people who are still taking drugs or alcohol.
You can try to help him if he admits that he has an addiction. I know it might be a long shot, but I’ve seen it happens more times than you know. Having a conversation without confronting him and telling him how hurt and sad it makes you feel might help.
If that’s not an option anymore, well….. it’s up to you to make your own happiness and whatever you choose to do, make sure it makes you happy.
Hope that helps a little, and I wish you the best.
