<human>: Can you give me the gist of the text in a nutshell?

This post is concerning primarily my ex [F23] and myself [M24]

My ex's Aunt has been battling cancer for the last year and a half, and recently lost the battle. I was not super close with her aunt, but I was pretty close with her grandparents (the aunt's parents). I have had on and off contact with my ex since she broke up with me last January, and she has kept me up to date on her aunt's health. 

Anyway, last week she told me the news when it happened, and then a day or two ago, she informed me her grandmother told her to ask me to come to both mass and the reception for the funeral. I was hesitant to agree go, because I didn't want to be a distraction (this would be the first time I would see her family since she left me). I voiced these concerns, but my ex said that it would help her grandparents if I was there, and her whole family wanted me to be there because 'they love me' and still want her to be with me and still think she is going to marry me one day. 

The whole situation makes me uncomfortable, but I would to help if I can - but am worried that my being there might bring about some unneeded drama. I am not concerned with behaving inappropriately myself, but I'm concerned that her family might end up asking me questions which I will not be prepared or comfortable with answering, based on my ex's comments on how they feel about me and still want her to be with me.

Does anyone have some advice for how to handle the situation?
<bot>: My ex's family apparently wants me to come to her aunt's funeral, but I'm worried my presence may potentially cause some drama.
