Ladies please help!

i made a terrible mistake. I was supposed to go to my boyfriend’s Military meets, but my transportation to there had a appointment with somebody and i feel like i stood by Long distance boyfriend up. I think he should understand that i cant control it. I love him so much and i cried like atleast 20 times today because I probably embarrassed him. I’ve offered to Skype, but he hasn’t replied. I love him so much...Please help
