You could have taken this approach or just told her there was nothing to discuss unless you want to work on the MR. Just show her a strong, confident, calm and cool M that doesn't get emotional, who is secure with himself, who is not needy and see where the conversation goes. Have no expectations and just be honest. Maybe she needs some closure or maybe she needs to know you still love her. If it starts to head down that path, make her wonder, make her chase you, be the prize.
