I see. Well for starters I think it's easier to find a man that's willing to be a bit more open about this lifestyle than women. I lucked out when I found our gf, but aside from her, there aren't too many women out there keen on the idea of my lifestyle.
I think it's nice that she's trying to be supportive, but I think maybe she needs to go about it a different way? Telling you that you're not living up to your potential isn't necessarily a great way to give someone a pat on the back. And, while I know she's not doing anything wrong, maybe she can slow down a bit more so you can feel a bit more comfortable? I know that may not seem fair, but one thing I learned in this lifestyle is that you have to go at the pace of the slowest individual.
Live life to the fullest 'cause you never know if you're gonna wake up tomorrow!
