Stick to the basics of old fashioned courtship. You have to prove you are trustworthy. If this is the beginning of your relationship, then you haven't earned the right to know everything about her, this goes for PRSD and non PTSD relationships. Don't let your heart go before your head. Stick with the basics, likes, dislikes, the usual dating stuff. Give her and yourself the gift if time. If you are consistently there for her in a non judgmental capacity which also means no pushing, she will eventually open up bit by bit. I am going to be blunt, but keep your gonads to yourself for awhile ( I am at work so don't have time to skirt around the issues :) ).Earn her trust by being a true friend first, enjoy her company, let her enjoy yours as well. And for God's sake don't go and profess your love after 2 weeks or even 2 month of dates. She will tell you what she wants you to know, when she wants. So no expectations beyond a decent fun friendship. If it is meant to be, it will progress on its own, and she will learn to trust you.
The last guy who pushed too soon for me to trust him, ended up being the biggest liar on earth worthy of an Oscar. You can bet that if there is another guy for me, and I don't believe there is, that he will have to give me Time and more time. It just makes good relationship sense in general.
