<human>: So I've been seeing this guy for almost 2 months and we just decided to become an item about a week ago.  I have never had such strong feelings for someone, I love and am attracted to him in every way. 

With that said, I may have drank too much last night and let a girl kiss me in the middle of a bunch of people at a party. I honestly don't remember any details - who the girl was, what she said to me before/after, who was around to see - I was a little shocked, but being more of a lover than a fighter (and too drunk for my own good) I allowed it to happen as opposed to shoving her off or turning away. 

No excuses, but here are a few facts anyways: I am still getting used to being in a relationship (been single for the last like 3 years), it happened really fucking fast (like, she grabbed my face and moved in for 1 second and the kiss lasted 1 or 2 seconds, pretty sure no tongue was involved though), I was too drunk, and it wasn't like it was a guy...?

I know I should've probably turned away but I didn't and then I forgot to tell my boyfriend last night that it happened. I remembered today that that had happened and called him to tell him and talk about it. He got very quiet and eventually stopped talking altogether so I hung up and texted him to call me when he felt like talking. He responded If**... 

It's been a couple hours and I've texted him again saying I love you and I'm sorry and you should know I'm entirely yours.... Tried calling again but no answer...

I don't know what to do and would absolutely hate if I lost him over this. Any advice or input??

Provide a brief overview of the text.
<bot>: I fucked up by getting too drunk at a party and let a girl kiss me. Boyfriend of 1 week was elsewhere in the house and I forgot to tell him until today. Now he is very upset and ignoring me.
