Sounds tricky...
OK, so you both get on very well, enjoy each others company, have good communication and trust each other but at the momment you are "friends" and she still has baggage from her last relationship. I wish I could say I haven't been there but I have...
If something is going to happen I think she has to feel that its her decission and that the timing is right. Otherwise there is the danger that she'll accusse you of going back on what you said you wanted especially now she's opened up to you too and is feeling vulnerable. You have her trust but if she thinks you've used that trust to serve your own hidden intentions she won't like it. You will lose that trust and it will be very hard to ever get it back. Remember she's allowed to change her mind whenever she feels like it because she's a girl. On the plus side girls are fickle and certainly do change their mind... even when they say that they have concrete views about something.
If you do want to foster her feelings for you, I'd suggest keep having fun with her but try being busy once in while and do interesting things without her. If she is into "you" and not just looking for someone to sponge attention off then by seeing you less often it will help her to realise it. She will think about you more and appreciate it more when you are free. It will also give you interesting things to talk about when you see her next. In addition it will help you to think about her less because you will realise you can have fun without her preventing one-itis from setting in. If you have fun with other girls it will raise your own confidence and perceived worth to her.
Important point one: If you do decide to pull away from her slightly it musn't seem like its an active decision or ploy. As she knows you very well she may see through this and spot its a reaction to the heart to heart you had.
Important point two:: She mustn't ever think that you are waiting for her or
that she can have you whenever she feels like it otherwise it will not happen. Be seen with other friends and women having fun too.
Important point three: Don't tell her about other girls to make her jealous. Girls spot this a mile off. Its better if you wait for her to ask you about your love life. If she does and seems more interested than she should be its an IOI. It may also give you opportunities to tease her.
Hope this helps even if you've already come to similar conclusions yourself. Good luck
