Nictea, I might be hurt over this, it’s true. But I wouldn’t freak the least little bit over it.
I throw parties all the time that my friends don’t come to. (Wait, that sounds bad. Lemme rephrase). My wife and I throw parties pretty often, and friends sometimes come and sometimes don’t. Sometimes they show up for just the first part of the party and later go to a different party (ours tend to be early-evening parties); sometimes they show up late. Sometimes they say they’ll make it and end up not showing up because they were feeling sick or just antisocial.
Is it rude for them to say they’ll be there and then not be? Yeah, kind of. Do I freak out at them for it? Oh, HELL no: the freaking out is far ruder than the not showing up.
Instead, I just know not to count on them being there next time. That’s okay; some friends are more reliable than others.
You ask, “Is it too much to ask to have someone treat you the way you would treat them?” I answer, YES!
You can’t expect people to treat you the way you would treat them: clearly you’re not treating B the way B would treat you. Instead, you can ask people to behave decently toward you. B has done so; you’ve not returned the favor.
Listen, I know you’re disappointed, and I can sympathize with you for being disappointed. You were looking forward to spending the evening with B, and it turned out you weren’t able to do so. It’s possible even that he flaked out a little in accepting another invitation, not realizing that he’d kind of committed to your party.
But if he flaked out, it was only a little flakeout. Your reaction is totally out of proportion. I’m trying to tell you that nicely; others are being less patient with you on it.
If you value the friendship, you owe him an apology – the sooner the better. Chances are good that if you apologize to him for your huge and unacceptable freakout, he’ll apologize for his minor flakeout (even if he didn’t really flake out – I’m still not convinced he did). That’s often how apologies work.
If you don’t apologize, he’s likely to write you off as totally psycho – especially if, as you suggest, this conflict between the two of you is part of a pattern. The lesson he’ll learn is that he shouldn’t accept invitations from you in the future. And he’s likely to tell other people about what happened, just as you’ve told other people about what happened – and you’re likely to develop the kind of reputation that isn’t conducive to people accepting your invitations in the future.
Yes, you’re hurt. Yes, you’re disappointed. You still owe him an immediate, unconditional, contrite apology.
