No, I really didn't date other people at all before getting married. In the first marriage that actually hurt me a bit because I was very young (got together with him when I was 17) and had no idea where my personal boundaries were or what I could and could not accept in a relationship. I'd never really seen a healthy relationship in action, and kind of assumed that since mine looked better than all the other bad relationships around me that it must be okay -- I was unhappy, but convinced myself that it was a fault in myself that I needed to fix.
For my second marriage, I love the fact that my husband never has occasion to question my previous life, and I do not have people to compare him to in a potentially unfavorable way. While I still didn't know my personal boundaries when I got into the relationship with him, he respected me as a person enough to step back and let me learn for myself. We live in the same small town where I went to high school and lived for quite a few years, and it makes me feel great knowing there are no ex-boyfriends lurking around the corner that might make my husband feel uncomfortable or possibly insecure. There are no skeletons in my past relationship closet that might pop out, and no memories to distract me from the wonderful relationship I have now. I think it has also helped in that I didn't have preconceived notions about what should happen in the relationship or who my husband should be, I was able to just go into it eager to spend my life getting to know him and enjoy the chance to be closer to him than anyone else on earth.
