Ask her out on a date, and during dinner, or drinks or whatever your date entails, while you’re talking, mention that you’re going to be a legally single man in less than 60 days! You can say just that or spin it any way you’d like. The important thing is to get it out there. I’m positive she’ll ask you questions after that, and the conversation will ensue.
It’s important to find out if the person you’re dating is actually available so neither one of you misleads the other one. There actually are married people who date under the pretense of being single and that leads to big drama and upset when the truth unfolds. So, be straight forward, and just tell your date your legal social status, and ask her how her divorce panned out (if she’s divorced) or if she’s ever dated anyone who was divorcing. It’s a way of getting to know someone, and after a few dates you’re entirely in the right in terms of manners to inquire.
Good luck! 😀
