Is OTHER wrong in the post ? POST : Throw Away because peeps know my account 

I used to be a scrawny dude and basically looked like Shaggy from Scooby Doo. 

So last year I went to a party. My friends encouraged me to talk to this girl. I've heard about her as we have a few mutual friends. ( let's call her Kaitlyn ) I saw her and let's just say I was interested.

I approached her and tried to talk to her and the conversation went like this.

Me:hey wh.. ( she interrupts me)

Kaitlyn: EW GROSS 

Me: what?

Kaitlyn: go away creep.

I think she began to shit talk me because people started giving me the stink eye and some big burly guy began threatening me so I decided to leave.

I would say six or so months ago I decided to change my a style bit I got a new haircut, new glasses and did some lifting. My friends say I look amazing and I agree. After the transformation there's people who still don't recognize me.

So yesterday I got a message on facebook from Kaitlyn she wanted to talk over coffee. I just ignore her. Later that day a mutual friend told me Kaitlyn really wants to go out on a date with me. I told my friend I didn't want to go out with Kaitlyn as I am no longer attracted to her. My friend told me that I'm obligated to at least go out on one date with her as I was previously attracted to her.

Kaitlyn messaged me and called me an asshole. A few of our mutual friends are calling me the asshole. Some of them are saying I'm obligated to at least go on a date with her. So AITA
