Hi Cookie
Sorry to hear of your situation, head over heart I guess is what you’re faced with.
Your life has seemingly changed relatively quickly and that is down to the powerful forces of the drugs.
The relapse your partner had was blamed on you and he shunned his responsibilities or acceptance that only he had control over this. You didn’t make him do it.
Let’s be clear, you have nothing to feel guilty about. He’s brought this upon himself. I as a recovering cocaine addict know all too well that you can blame others for your ill conceived actions to deflect the reasons why you do certain things. Hence why acceptance of who you are is so very powerful.
He could be lucky and have an awakening before it’s all too late or suffer the consequences of such an existence. He has to stop for himself first of all, not for you or the kids. Only then can he present himself authentically to the world.
I’d reiterate you have nothing to feel guilty about. You can help him however he has to help himself first.
