Jolinda,
I'm not sure if you've checked your private messages. I messaged you some info that might be of some help to you
I know how isolated and lonely being in love with someone who is dependent on a substance can be. I am hear for you if you need someone to talk to.
Feel free to message me anytime and I am more then willing to give you my number if you'd like to talk via the phone.
Keep walking in the direction of trying to understand addiction it is in the journey that you will find yourself and the strength to become free.
Co-dependent No More will be very helpful and bring much insight to you. I sent you a link to a site that is geared specifically towards methamphetamine addiction. It is a great site. Very informative. I think you will find it helpful.
*hugs*
