need help to support

Hey People, I have some questions and I hope you can help us. My fiancee has come out of the closet so to speak and told me about her habit. I was surprised because I never noticed but when I think back all the signs were there. I think it was a huge step for her to come and tell me too. Well anyway we know there is going to be no easy way to overcome this condition but we are going to try and I really want to support and help in any way I can. I have been learning more about trichotillomania and now there is also dermatillomania. I am not going through it so its a little hard for me to understand the feelings and motivation behind the habit. One question I have is when I tell her to stop, it could cause resentment as I have been reading so if someone wanted to help make you stop, how could they do it without causing resentment? Also if someone has helped you how did they help without causing more trouble? Has anyone conquered the the picking or hair pulling? or is it something we have to learn how to live with? If you are a conquerer, how long did it take? Any other advice for someone trying to support a person with this habit would be greatly appreciated. Thanks for any advice. Its really appreciated. P.S. There are people out there who want to help but just dont know the best method so dont be angry at them help them to help you.
