Sounds to me like this friend isn't a real friend bro, I think you're better off dumping that zero. This person should be ashamed of how he treated you.

wow...harsh

It happens sometimes.
You make plans with someone, and you don't wanna break 'em.

I mean, he could have asked if you wanted to go hang out with those other people, too, but I know I have different groups of friends who don't necessarily always want to hang out with eachother, and sometimes I just have specific plans with specific people. He probably didn't mean anything by it, and at least he was open to hanging out the following week when he didn't already have plans.

Lol, but the thing is, this has been her excuse since July.
She's only had a job since the end of August.

It's the finer details I didn't share. :P
