Mine is like this too. He is also addicted to coke although now he turns it into crack. He sometimes has a sex drive while on it but he’s not loving – it’s just sex.
It is the lack of affection and intimacy that’s missing. It’s like we are roommates not partners. He doesn’t want to chat with me anymore. He finds everything I do irritating and says he doesn’t love or like me anymore… so I’m leaving. I can no longer hold any hope out. I’ve waited for 2 years now and it’s only getting worse, not better.
