SUBREDDIT: r/relationships
TITLE: Im [28m] a lot more attractive now than when I first met girlfriend [29f] of 3 years. Play the field or stay in relationship?
POST: When I met Amber I was skinnyfat and broke. Fast forward to today and my career has taken off beyond my wildest dreams. Im making craploads of money. Last summer a bodybuilder friend of mine introduced me to HGH and steroids. Ive done a few cycles since and my body is amazing.

I get A LOT of attention from women. Which is bittersweet as I used to be treated like I was nonexistant. Horny thoughts bombard my mind all day.

My gf Amber has pretty much stayed the same as when I met her. Shes not very ambitious and average in looks. I feel comfortable around her but I have this strong urge to see what else is out there, all those sexual opportunities I didnt have before are here now... but I also feel guilty and selfish thinking this way.

And I feel worse knowing that a year ago we were planning to possibly get married and start a family. My parents like her and her parents adore me. I get along with her siblings etc. It would suck to have to build all that up again. 

But still...
TL;DR: 
Who I am has changed dramatically since I met my gf. Wondering if I should break up with her and see what else is out there. What would you do?
