Hi Ambaj, really sorry to hear you are going through this – it’s so awful watching someone you love do this to themselves. It doesn’t sound like your boyfriend thinks he has a problem yet which would be the first step to getting himself sorted. I would read some of the other posts on here and that will give you some insight into how it generally goes having a relationship with an addict which isn’t positive unfortunately. Having said that some do get themselves clean and recover, I know a few that have and now happy, but only once they admit they have a problem with it and make some real effort to stop – it’s not easy at all. You need to protect yourself in the meantime.
I would suggest he calls cocaine anonymous and gets some help. And set some boundaries – if he wants to do it he should go somewhere else maybe so it’s not around you and your family. You say his marriage has broken down and I wonder if that was to do with drugs?
And on the stress point – coke makes you extremely anxious and paranoid and like you’re a terrible person, so it’s a vicious circle of then having to do more to block that horrible niggling feeling out temporarily, only for it to come back worse than ever.
Take care of yourself xx
