<human>: Can you summarize the given text in a few sentences?

Long story short:

I've always had a huge thing for this girl that I kind of know. Usually I'm not the type to be bashful but she made me incredibly shy but I still always talked to her and it always felt like we had a good connection.

Anyway flash forward a month or so and we are at a party last night (my best friend and I) and who should be at this party but the girl. Now my friend knows all about how I feel about her, but decided he would not give me time alone with her so I can make some kind of move or initiate something or whatever. Every time we spoke he came by and hung around, and I was like okay whatever.

Anyway she has to go to the bathroom, I go upstairs to get some water and I talk to a friend of mine for a while. I can't find my friend or the girl anyway, write it off, I look at the time and realize it's late and I am going to walk home.

As I leave I see my best friend and the girl in question making out in the front yard, and my stomach kind of just drops. He looks and goes "hey man!" and she says "seeya later bucketheadland2!" and I just kind of smile and wave like the bashful person I am and walk home sad.

Anyway, I am at work now and am still kind of pissed of at this and I don't know if I should even say anything to my friend. It feels like a problem I had in highschool and thought I'd be mature enough to not care about this. One one hand, all's fair in love and war and they can do whatever. BUT we are very good friends and he knew how I felt, and I've been in a similar situation where I stepped down because I knew how my friend felt about the girl in question and things would just be awkward.
<bot>: Friend made out with girl he knew I was really in to, feeling pretty down about myself, not sure if I should say anything to him or move on.
