My friends mom died and she doesn't want me to go to funeral or breakfast...

How do you address a friend whose mom just passed and she doesn’t want you to go to the funeral or breakfast afterwards?

I told her that I would like to go as a support to her and she told me I don’t have to go and that her family support her.

She is a friend for 25 yrs but has not wanted me to be around her family for all those years so I am not close to family but I am close to her. I have been honest, loyal, invited her to go out with me and my other friends and she turns everything down. She never invites me with her friends either or when her and her sisters go out.

I addressed her honestly with this and she keeps skirting around the topic and never giving me any substantial reason why she is excluding me from her family get together’s for 25 yrs. She also is like this with her friends and her boyfriends. All of our time together is one on one. I feel like she is hiding me for some reason and she will not tell me.

What should I do about the funeral issue which is today and the excluding and not inviting me with public events with her sisters and her friends?
