<human>: Give me a shortened version of the text

OK obligatory stuff first I am a 21 male she is a 21 female and we have been dating of over 2 years. Her parents are divorced. 

Alright, so both my girlfriends grandfathers are dying and might die around the same time. I dont really want to go to one of them because her father absolutely HATES me and I don't really feel it is my place to go to his dad's (her grandpa) funeral since I really only met her grandfather twice and I feel its going to cause serious issues if I do go. With that I don't know any one on her fathers side of the family and they all generally treat me during the few gatherings on that side I have been to with a general sense of apathy and restrained hostility.

 On the other side of things I am OK with attending her grandfathers funeral on the mothers side, mainly because the dad will not be there. My girlfriends sister does hate me (but she doesn't show it too often) I feel since I went to their grandmothers funeral on that side of the family a year ago and it didn't go badly as I am very familiar with the mothers side of the family so it feels appropriate for me to attend. Also they all generally like me on that side.

Final note: I live currently 3 hours away at a University, but I will be returning home the last full week of the month on spring break so this really wont matter unless the funerals happen during that week I have off. I have already expressed to my girlfriend about my reasons for not wanting to attend the one funeral and she is absolutely pissed at me, which is why I came on here to get random strangers opinions about if I am being an asshole.
<bot>: Girlfriends dad hates me, don't want to go to his dads (her grandpa's funeral because of it)
