Hi mate, I hope you’re okay.
This is a horrible situation you’re dealing with and I know how hard it must be for you after so long together all of a sudden not recognising him.
What’s bizarre is that you say he’s been only using for the last 6 months after the early years etc.
Have you asked him outright why he is using coke? What’s changed to make him want to use it because I can assure you that it isn’t enjoyable when it’s at the point you’re lying to your partner and it’s affecting your relationship. Where is he using can I ask? Is he doing it openly so that you know or is it a cat and mouse situation?
No one ever wakes up one day and decides that it’s a good idea to destroy their life and become an addict and I’m sure deep down the man you married is still in there.
You’re obviously aware of his addiction and he knows you are so maybe the best thing now is cards on the table. Ask him the hard questions, the whys and when’s and the hows and offer him a life line. If he is remorseful and has sadly fallen victim to addiction and wants to work towards getting back to his sober self then please.support him as much as you can. But equally if he is not willing to accept his actions can’t continue then take the necessary measures to safeguard yourself and your family
Sending love
