<human>: Give me a shortened version of the text

So I have been best bros with this girl for eight years. We dated for three of them. We thought that were were going to get married, but we're not. We broke up in August, it was tough getting over it but I have moved past it. I dated a little bit non-seriously and now I think I am ready to try again with new folks for real.

This isn't a pressing concern right now, but I know it will come up, and I want to be prepared. I am maintaining my best-friendship with this girl. When I find a new serious relationship I am aware that this will be intimidating for anyone new in my life. The book on me and my best friend is closed and we are both comfortable with where we are. I want that to be clear to anyone new in my life. I am not going to lie about our history or pull away from our friendship. If I were to get married tomorrow this girl would be my best man.

Ideally I will meet a woman who totally understands this relationship. But I know that is wishful thinking. Has anyone in the reddit-verse been where I am and what did you do?

I feel like I should add that my ex is objectively attractive. I know this makes matters worse.
<bot>: My best friend is of the opposite gender, and we have a history. How do I make it clear to my next serious lady-friend that she doesn't need to worry about my ex.
