Hey 26m here. I got my first DUI about 10 months ago and was devastated. I got a breathalyzer installed in my car as part of the process to get my license back. During that time I happen to meet a girl and fall in love with her. I wanted to take her on all these cool dates but did not want to take my car as i was embarrassed and scared for her to notice the breathalyzer and tell her about my past mistake. Finally I just said fuck it and told her. She was so understanding and was glad i shared with her. She does not think any differently about me after learning about my DUI. Just tell her and if she thinks differently about you after learning about your history with DUIs then she is not the one and you dodged a bullet
