GF invites me to wake, whats my line?

[The Man]

So her grandfather died after alot of hospitalizations, and she definatley saw it coming and so did her family but she isn't taking it well. I have to drive awhile and meet her family, which i've never done, and I really don't want to go. We aren't very serious. Is it -ev to just say "I don't want to go." and be honest?

I don't think lying is a good line... and I wouldn't expect her to attend a wake for my family and I doubt I would even invite her unless she knew the family member.

need help =-0
