You ask a question so many parents ask here. It's so hard to know what to do, as parents we want so much for them know we love them, yet the hurt with no contact runs deep. I've never had to ask that question My D has always lived with me. If I were faced with it I would definitely maintain some kind of contact. Like you're already doing. Just a note, a text telling her I love her, miss her, ask her if she needs anything. For me the one thing I would not do is ask for forgiveness. I know that sounds cold but, I can say I know I didn't cause my d's illness, I didn't do anything to add to her perception of fear and pain. Just be there for her, she needs to know that a least one person in the world cares about her, no matter how mean she may be. I would suggest reading a few books. I started with "I hate you, don't leave me". It was like reading my own story, it changed so many things for me. Sending you hugs, we are here for you. I'm sure another parent will come along who has been through no contact, to share with you too.
