Wow you are pretty strong to block her and very aware. I am impressed by your level of awareness about what is going on. I would be hacking her face book account lol.

Your sobriety and mental health has to come first. When I first got sober in AA I found out I was a rescuer. They were going to make me a t-shirt "Rescuers Inc.". I wanted to be the night in shining armor rescuing the damsel in distress. Usually I got in relationships with someone who just got divorced or just got out of a long term relationship. They needed me emotionally for about six months and then as soon as they started getting over it.........bam I was gone. And then I would obsess like crazy over it. One relationship was two years and was actually very healthy. She had twenty years in Alanon. She couldn't handle my depression and our age difference. when it ended I got triggered and would listen to her voice mails and read her emails. (I had her passwords) I tortured myself for about six months (of course another guy showed up in the emails). Finally I found the strength to move on and get over it. Oh the good ole days of early sobriety.

Anyway. Real love and caring are involved for sure but relationships can be very addictive. Maybe you have an unhealthy need to fix her. Just because we are alcoholics doesn't mean we are not codependent. It is after we get clean and sober that our co dependencies come out.

I would strongly suggest Alanon. It is what helped me a great deal. There is no way I could be with an addict that was actively using at this point in my life. I won't tell you what to do but if it was me I would cut it loose as hard as that would be. Maybe postpone the marriage and give her a set time to really get clean and sober. I wouldn't have high exceptions of her changing though. You have to take care of you. Check out Alanon.
