Truth or ideals you say? To add onto this so it wouldn't be a worthless bump, I kinda have mix feelings about this. You just ended a 5 year emotional relationship with your girl to try your chances on being with the fat one. Most will call you stupid, but once you start losing sexual interest in one person than the relationship is pretty much over. Plus she let you be open and explore other girls. Shit was doomed to fail from the start of that. You already done did it now, so hopefully the fat girl will be good for you (and to you as well). Good luck with her.
