How can I get over my crush on my married friend?

I’ve posted this problem in a few different places. I’m trying to get a number of opinions.

I’m a 17-year-old guy, and I recently started working at a place where I’ve been volunteering for 2 years. I became second-in-command to a female friend of mine, who’s 23. We see each other every day, from 9 to 5.

I’ve always thought she was cute, but it never really occurred to me to have a relationship, because of the age difference.

Recently, I found out that she married her boyfriend and took his name. It wasn’t really a secret wedding, but they waited a few weeks to tell us.

Since then, I find that I’m crushing harder and harder on her, to the point where I’m feeling heartache.

I know that I can never pursue a relationship – she’s agreed to spend the rest of her life with this guy. I’ve met him a couple of times, and he’s a really good dude. They seem very happy together, and I should be thrilled with that. But I can’t help but feel bothered by it.

Personally, I think she’s a little young to be married – and I think her husband is in his 30s – but I know it’s none of my business.

I was also kinda shocked/confused by the fact that she changed her name. Again, none of my business, but it does upset me!

I’m not about to confess this to her – I would never want to sabotage their relationship. I think marriage is a wonderful thing.

She likes me platonically, and we share a lot of the same interests, and I think we could have a really great platonic relationship if I could just get over the awkwardness that I feel around her.

She just personally invited me to a “wedding celebration picnic” that happens in less than 2 weeks. I feel like attending it would either provide closure or make me feel a trillion times worse. I don’t know what to do.

It’s also a bit troubling that I only really started crushing on her AFTER I found out about her marriage. What does that say about me?

I’m 17! I shouldn’t be worrying about this stuff!
