I Have Recently Met A Woman/girl Who I Am Sure

I have recently met a woman/girl who I am sure has Dissociative Identity Disorder. She does not know it but does admit to having an alter ego. I have triggered these changes , unintentionally, by asking her things like, "where did you get an idea like that" or using common phrases like "I love her" meant in a friendly way. These phases and just about any thing I might say are usually in texts and can set her off. At one time she seems like a young teenager full of hateful cuts and very , sometimes totally , unreasonable , just will not listen to aby reason. At other times she writes the most beautiful words and phrases to me, very personal loving things. Other times she is a pragmatic 67 year old adult that understands deep emotion and logic. She is , BTW , 67. When these very distinct personalities have control the other qualities will not appear. Sometimes she will just turn off like a light switch with no indication of why or any warning that something might be wrong or might change or anything at all. I try to reach her with words and get no response. Then at some point I might gently touch her arm or hand and she jumps and looks at me like it takes her a few seconds or minutes to know who I am or where she is. We had been communicating for over 8 months and she had agreed to sing a lead vocal in a song I had written. I , of course , sent her the song . She said she loved it and wanted to sing the part. We talked about this many times over the 8 months leading up to my traveling to her place and taking recording equipment for that purpose and to get to know each other. Many days went by before we got a chance to record and I asked if she was ready to work on the song. She said , "What song?". That of course floored me but I put the song on anyway to remind her. I played the song all the way through and she literally did not remember it. I said , "You don't remember this song?" " This is the song that practically got our relationship started" "We talked about it so many times" . She said no .There are many incidences that describe these changes of personality but too many to list here. I'm not sure what my question is . I'm very concerned for her and it puts a tremendous strain on what I thought was a wonderful beginning. Thank You, My e-mail: YYYY@YYYY
