Should I attend the memorial of ex-girlfriends mother?

I was with my current ex-girlfriend for about 2 years. The breakup was bad, but I had to do it because I discovered I wasn’t ready to commit, but she understood.

Her family loved me, and I befriended them as well, although her mother had ALS. We have been apart for about 2 months and she just contacted me to inform me that her mother finally passed away.

She said she does not care if I go or not (to the wake, I mean), but I haven’t been in this situation before so I don’t know what to do: I want to pay my respects and see her mother one last time, although I’m not sure if this will be seen as leading my ex on to potentially get back together or something. She still really loves me and I don’t want to hurt her again while she is healing. Should I go?
