<human>: This may seem a little childish, because most of you are probably older than me. But please hear me out. I've been talking to this girl for around 9 months now, she finally got to my school and tomorrow was the day I was gonna ask her out. I get home and formulate my plan. I check instagram in my break and see a picture of her holding hands with another dude. 

In my blind fury and sadness I snapchatted her "So I heard you and [guy] are dating?" (I almost laid all the cards on the table, but decided against it) she said they weren't official yet. Now I am (was?) almost certain this girl liked me back, we talk damn near every day, the longest we have gone without talking in the past couple weeks is 1 day. She's admitted she likes me before, and I have a feeling this is happening because I havent made a move yet.

I want to get to her before they are official, this guy is a douche, and I really like her. I never want to feel what i felt when I saw that post again, and it will only get worse when they become official. I need to interrupt that, and I don't know how.

I don't care about the other guys feelings,  I just need a method to do this, no matter if he gets hurt or not, I dont care. If any of you have some advice here please help me. This girl is amazing, and I want her to know that.

Provide a brief overview of the text.
