It’s such a hard thing to process having a loved one who is an addict. I personally have tried to separate myself from the situation. My addict is attending regular support groups and saying they are determined to get better but at the moment I cannot believe anything they say. Part of me does not doubt the intentions they have but for my own sanity I cannot allow myself to be sucked into the rabbit hole of the lies if it turns out not to be a ‘true’ recovery.
Where possible try to protect yourself and your family from any financial fall out from your partner by seeking advice from a professional.
I understand your feelings of loving your partner but if he is addicted to coke his brains been hijacked. It sounds like he needs help but please look after yourself in this situation. Sending lots of well wishes and support
