so i invited a boy to my work's winter party. we're friends. i planned for us to go as friends. it was rather short notice. i think i asked him on tuesday. he said yes he wanted to go and to call him with details on saturday. so i told him to meet me at a certain time at my apt and we would go from there. i did forewarn him that it probably wouldn't be too exciting but that i had to make an appearance and we could leave early and go do something else. so he then texts me less than 10 mins before we're supposed to meet to tell me he's going to be late because he has to go bail his roommate out of jail in vancouver. i tell him thats fine and if he wants he doesn't have to go, we can just meet up later. he replies with no i want to go i'll text you when i get there. he never texted. around 9pm, about 2 hours after we were supposed to meet, i text to him ask if he's still coming. he says hes still in the couve but he'll try to get there as fast as he can. an hour later i leave the party. i text him to tell him i'm leaving & that if he wants to meet up later to get a hold of me. i haven't heard from him since. this morning i sent him a message on myspace. i told him i wasn't really mad, more disappointed and that all he had to do was tell me he wasn't going to make it, not keep me waiting. i thought he was a better person than this. if something happened or he didn't want to go all he would have had to do was tell me... sorry i cant make it... not only did i have to pay for his ticket but i had other friends who did want to go. am i wrong to be hurt by this? is it wrong to at least expect some type of apology? friends don't do this to one another. we haven't been friends for long but that shouldn't be an excuse. he did read my myspace message but he didn't even respond to that. i just don't understand it.
