Hey confu, I think you're making a bit of a blunder of the situation
I don't think the point is whether she's hot or not and you current girl is so so. I'm not sure. Heck I haven't seen either of them. Speaking from experience, Im close to same age as you, 28. I left the Borg bout 5 years ago. I've had relationships in the Borg and outside in the 'world'. And I can say that worldly women seem to have their heads screwed on properly. They go to college and they know the game more than us in most cases. I use to be engaged to a sister when I was 20, (because as you know, everybody gets married in the troof about that age, just to get laid), and she was a stunner, absolutely gorgeous!
Well anyway we were together for bout a year, but due to circumstances things didn't work out. Why? Because it was lust not love. The same situation happened with alot of young brothers and sisters. My friends who were in the Borg, simplied got married quickly just after meeting a hot sister at the assembly. 3 months later they'd get married, (to get laid). Believe me my friends marriages are so screwed up and it's worse when kids are involved.
I'm currently living the best girl in the world, she's smart, beautiful and has a load of common sense. More than all the girls I knew in the troof combined. But it's your life mate, just let the big head do the thinking and let the little head do the fun!!!
Good Luck with your choice anyway!!!
