Hi, it sounds a bit like he has moved from one addiction to another i.e. First alcohol then cocaine. Also taking both is not a good combination as alcohol is a depressant and cocaine is a high. It also seems like he keeps pushing the boundaries and if you are not happy then you need to tell him. It may be that he has decreased his alcohol intake in order to take the cocaine. All I know is that with cocaine you have to nip it in the bud as one line once week or less soon becomes much more and then it becomes really difficult to stop. It doesn’t seem like your partner is admitting that he Has a problem and until he does that and he himself wants to stop there is very little you can do. If you read through some of the other posts on here about cocaine addiction you will get some useful information and advice. You take care.
