Hello and Welcome to JustAnswer. Your question is not closed until you are satisfied. I am happy to assist you with your question.
If this relative has a personality disorder, such as dependent personality disorder, there is very little you can do to get her some help, other than to encourage her to do so. The best thing you can do is to keep your boundaries firm. If you are going to refuse to give her money, for example, do not let her persistence in asking change your mind. Stick to your guns. She will only learn by consistent repetition and the establishment of clear boundaries.
Just curious: What pattern do you think she fits to a "T"?
Hi, sorry I missed the chat. The pattern she fits to a T is the one described here
and in two other places. I found these online because on Christmas Day, after having brought her and her baby by plane for several days at Christmas, I was experiencing stress at a build-up of indirect requests and complaints. I had noticed this pattern before for rent payments, computer purchase, clothing, etc. with myself and others but we mostly had telephone contact which was more limited. I am very concerned that she has a 6 month old baby, is single and low paid. So this makes it harder.
