Ugh Pax... I hope you can over come that insecurity that was the result of your relationship. You seem to have everything together and seem like a great person. I hope you see that.
I am kind of in a similar spot. I have been entangled with WW since I was 17 so, like you, that relationship has affected how I see myself and how I have projected myself. I guess the good news in all of this, is that we have figured how the relationships affected and changed us. So hopefully something that is we can work in the future.
