Oh, you are running away afraid to be crushed by the big woman.

BTW I doubt it's the woman who wants it first. Actually, I only know women trying to please men with their looks and everything. Once started there's no way back, and never satisfied. I assume it was the other man who wanted the big (he could feed her to get the volputuous if he likes it) and the ex was a good one to pay for it.
It sounds like an unhealthy relationship (the first and the present one) if you can't accept someone the way he/she is, it's doomed to end.

A good Monday dear @lupega. No need to always run away... (I already picture you running and bumping into a woman). LOL
