I'm very sorry you're going through this right now. Very stressful.
Number one, I'm going to suggest you go to the Friends and Family of Narcotics Abusers section a little further down this website on the forums section. Number two, I would urge you to seek out something like Alanon or Narcanon for friends and family of drug users. They offer support and help for people in your position. If they don't have NarcAnon, go to Alanon.
Number three, if there is any way you can open up a separate bank account for yourself or for your own paycheck, do so immediately. If you have your pay direct deposited into a joint account, have that stopped immediately and switched to your new account. The person that an addict becomes when they are using is not the person you fell in love with. They will lie to you, take money or valuables, and in general put their drug first. It's not sane, but that's the truth. You must protect yourself as much as you can financially or you will feel like an absolute fool later. You also need to get as much emotional, spiritual, mental health support as you can for you. You can't make another person get sober if they don't want to, but you can take care of you so that you're in a sane space so you can make rational decisions. Right now you're living in a hurricane. I wish you well. Take care.
