<human>: About two weeks ago she asked me to come with her family to her grandma's, which is about two hours away. I've already met her grandma and we get along great. We'd be spending the night at her house and coming back the next day. I told her it was a maybe, as I'll have to see what I have going on closer to when the time comes. Today she brought it back up - we'd get there on the 20th, and come back on the 21st or 22nd, so now we may potentially stay 2 nights. I just recently found out my lifelong friend that moved across the country in July is coming back on the 20th, and I really want to be there to see him. I explained this to her, and now she's upset with me. Am I in the wrong here?

Give me the gist of the text in a nutshell
<bot>: Girlfriend is angry I won't go to her grandma's because my lifelong friend that moved across the country is coming back on the same day. Am I being insensitive? How can I mend this?
