Hi Liberty
I’m so sorry to hear this. I think the harsh reality is you now have to put yourself first and ask yourself what do you want for yourself.
It sadly doesn’t look like he’ll ever quit so you have to sit down alone and think seriously is this what I want for my life ?
You can be his friend if you don’t feel you can cut him off but I think it maybe time to end the relationship.
You’ve done all you can and it hasn’t done anything
You’ve needed his support and all he’s been bothered about is his own needs/wants.
Unfortunately it seems that the drug is in full control especially if he’s upped his usage.
I’m so heartbroken for you that things have worsened for you, life can be so cruel.
It sounds like he’s given up and given himself to the drug take completely over.
I don’t think there’s anything left liberty for you in this relationship, you need to put yourself first it’s time to break away.
