She has not returned my call since Monday at 6 pm. She texted just now at 1pm. She says "I send you a hug. Let's see if we can talk today. I have not been feeling well"

So she saw I was not going to call her and now she is back. But don't know what to say when we talk. I don't think I should be forgiving mr nice, because she will get the message that she cad do this whenever she wants. She dis this exact same thing over the weekend and I was forgiving and understanding and she did it again. I think I should say something along the lines of " I understand you are under a lot of stress but I feel you have not been taking me into consideration in the situation I have been living with you in the last few days. This has to change otherwise I will be gone, I will not be your friend. I dont want this." I have to say something. I cannot simply accept this because she will lose respect for me. This is not one isolated incident. This is now a pattern of behavior that I have to stop. As I said, I have gone from being very attractive to her to not being attractive. There is a little bit left. She did text me and with a kind message sending me a hug. But I have to communicate that this is not enough for me. I need to be treated with respect. She also says "Let's see if we can talk today". She does not say I will call you today.

Any ideas on what to tell her? Does this sound ok? Should I be the one who calls at 6 pm or wait for her to call? Or should I just text her at 6 pm to let her know I am not mad and she can call me by saying something like "I hope you are feeling better". ??? I don't feel I should be the one who calls but I am afraid she might not call, get mad at me and lose what I have just gained. She wants to talk. I don't want to screw that up.
