Years ago, when my SO and I calculated our compatibility using OKCupid, there was a way to run a report on items that decreased compatibility. We didn't have many, but it was helpful to talk about the few things we did disagree on. I wonder if they were able to do something similar before their marriage; maybe it would have helped.
Sorry for your pain Alex, but glad to see you are getting to experience some wonderful new things. Thank you for sharing this touching piece.
