<human>: So my friend and I have had tentative plans to watch the world cup together for months.  So far these plans have not come to fruition.  He's been out of town for a couple weeks and I had to go take care of my ailing mother so no big deal.  

Two days ago I texted him to see if he was back in town.  If he was, I was going to see if he wanted to watch the game with me.  Turns out he beat me to the punch.  He said "yeah I get back tomorrow night (which is last night).  want to watch the USA game on sunday?" I responded enthusiastically "heck yeah!" and left it at that since he was gonna be on a plane for like 4 hours minimum.

So I call him this morning to flesh out our plans and he tells me he's gonna be watching the game with people from his indoor soccer team.  WTF?!  After having been looking forward to this for weeks, I'm super deflated.  I wanted to be like dude wtf we had plans on the phone but I was caught completely off guard.  Surely he wouldn't flake this time, given that we've been planning this for months and he's the one who suggested it!  So as usual I was polite and we talked for a few mins and hung up. 

He pulled a similar stunt when I hosted a Super Bowl party.  Not long before kick off I called him to see where he was and he told me he was going to another party.

I won't bother listing all the times he's bailed, but my gf has noticed his flakiness too and has said I need to address it.  But how?  Conversations like these are pretty foreign among guys (at least in my experience).  We just don't talk about our feelings as much.  The predominant mentality is that getting upset over something like this means you need to get better grip on your emotions, but I don't think just continuing to stuff it down is going to work for me.

Condense the text into a few key points
<bot>: long time friend keeps bailing on me for other plans and it's been getting me down.  How do I address this?
