Is AUTHOR wrong in the post ? POST : I had a buddy that was my best friend for 15 years.  He went out on a couple of dates with a girl and that was the last I ever heard from him.  No reason, no responses from phone calls or texts, wouldn't answer his door if I swung by his house to make sure he was ok after not hearing from him.  After a month and a half of trying to contact him I called it quits with trying.

Fast forward 5 years to when he ran into my mom at a gas station and then all of a sudden he got my number from her and wants to hang out.  I've since started a family and he doesn't really know a thing about me anymore.  I end up hanging out with him and his now fiancee.  I don't even recognize him cause he's not even close to the same guy he used to be.  

A couple months later I get an invite to his wedding and then a text to be part of his bachelor party.  I then come to find out that all of his groomsmen are the same guys we all grew up with and from the group texts I was in for the bachelor party that none of them ever got cut off like I did with everything they were talking about.  He never once gave me a reason for dipping out of my life for 5 years, even though I was the only person he did it to.  

AITA for not going to the bachelor party and for sending in my rsvp for the wedding with a no?  I personally don't feel like going and hamging out with all the guys I grew up with who for some reason weren't shut out?  Not to mention that between the bachelor party and wedding it would cost me over $1,000.  

TL:DR - Best friend of 15 years stopped talking to me out of nowhere and then 5 years later wants me to be part of his bachelor party and wedding and I said no.
