So, a close friend of mine is getting married in less than a month. She introduced me to some of her friends about a year and a half ago, and I've gotten really close with them, too. I'm going to be driving to her wedding with a couple of them.
There is this other guy that is a part of this group. He and I became friends immediately after she introduced us. We talk almost on a daily basis and we hang out at least once a week. He loves her very much, he is very fond of her because she helped him through a breakup. The thing is that she didn't invite him to her wedding, and he is kind of expecting her to do so. He thinks they are really close, but he doesn't even know when is the wedding or where.
I can't help but to feel bad for him, since he is expecting to be invited. He's asked before about the wedding, and I change the subject or lie to him, telling him I don't know anything. I'm afraid he'll get mad at me when he finds out that I knew. I don't want to lose the friendship but I also know it's not my place to tell him anything. How do I approach this?
