I am so broken up about this I don't know where to turn, except for a message board. Here is the situation: my best friend is a guy I used to work with, who has a girlfriend in Colombia, but lives and works in the U.S. We once had a painful falling out, but about a year ago we reconnected and became friends again and since then we've been besties. When we go out together, we often go see a movie, go to dinner, and afterward sit in a bar or coffee shop and giggle for hours, and he generally pays for everything (he insists). We recently went on a ski trip together. It's all platonic though, he has a long-distance girlfriend so other than hugging and occasionally holding hands and staying up late at night to talk nothing more has happened.
I admit I have a bit of a crush on him, but I've accepted that he has a girlfriend, so I'm content to be his friend, and that's it.
Well about a week ago I told him about a guy on match.com who wanted to date me, and I was a bit hesitant going on a date with someone I didn't know, and asked him for his advice. In the past I've asked him "boy" advice and he's always listened patiently and given me advice. This time he was very curt, and said yeah, sure, why not, give him a chance, can't hurt to go on a blind date. Then he said really testily, "Don't blame me if anything goes wrong, it's your call," and then said he had to go write a paper, and couldn't talk anymore, and we ended the convo.
Since then ... nothing. He hasn't called me, or texted me, or written to me. He's never gone that long without talking to me. Yesterday I text messaged him and he usually responds within seconds, but this time ... nothing. I am so hurt and confused, surely he can't be mad at me for going on match.com dates, since he himself has a girlfriend! I did not mean to make him mad, but I feel like trying to contact him again would make me seem pathetic.
This guy is my best friend in the world, he's the first person I tell anything to, and his friendship is very important to me. He's shown himself to be a good friend to me too, like just a few weeks ago I got REALLY sick and stayed the night at his apartment. I was basically ... crapping and throwing up. Instead of being grossed out, he stayed up with me while I crapped and threw up, let me sleep in his bed (he slept on the couch), and gave me his only blanket (he claimed he didn't need one). When he gave me the blanket he tucked me in like my mom used to, and I thought he was one good friend, a guy who didn't get grossed out by a girl who was throwing up and had the runs.
I'm so sad right now I can barely concentrate on anything. What do you think I should do?
