My SO is addicted to cocaine

I don't know what to do anymore. It started of as being a casual thing then all of a sudden he has been doing it every week, midweek, weekend. He even doesn't end up going to work the next day. I've had so many fights with him and he promises no more. We figured he is depressed because of his business failing and he got a referral to see a psychologist but didn't go yet. The worst thing is we are in the process of doing <a href="https://glowing.com/glow-fertility-program">IVF</a>. He has done it previously with <a href="https://glowing.com/glow-fertility-program">IUI</a> then calmed down and now again. He tells me he is serious about this but then he does this. Apart from this we have a very good relationship and love each other . I don't know what to do 😭. Anyone been in the same situation? I dnt feel comfortable telling my family. I've thought of telling his family but they live in a different country.

EDIT: (I've got anxiety because of infertility for 3 years but I haven't turned to drugs & we were both affected financially cause of business, I'd just wish he would seek help)

#2 Thank you for all your comments. I cried. Yes I definitely need to put my foot down and give him one last chance or I'm out. He will need to go therapy and <a href="https://glowing.com/glow-fertility-program">ivf</a> will be on hold. I hope I get the strength to stick through all this. Wish me luck. xx
