I love it when guys say, "I wasn't the greatest husband." What does that MEAN? HOW weren't you supportive of her career? What did you say? What did you do?
Just trying to help you out here, so you can be more specifically different moving forward, so I can maybe give you a bit of a glance in her heart. I smiled when you said you were an engineer...it seems there are more than their share of them here...all that "feelings" stuff.
