Awkward Bromance question incoming.
The current situation:
1. My best friend from high school is getting married.
2. We're not that close anymore. We meet up at Quakecon once a year and chat on Steam, that's pretty much it.
3. I didn't even realize he was engaged.
4. I find out when his fiance sends me a wedding invitation and a message on Facebook asking if me and another guy from high school will get together and have a bachelor party for him.
5. I assume if she's hitting up his high school friends to ask something like that, then he must not have a lot of close friends where he lives (he's about 100 miles from me) so I agree to do it
6. I tried to talk to him on Steam, he doesn't respond.
7. I talked to my other friend; he's attempted to call and text him, but he hasn't heard back from him either.
The question:
Is he done being friends with me, and am I justified in blowing off him and his wedding now? Or is this like some pre-wedding depression thing, and I should just drive up to his house and hug it out with him?
