I'm glad to come here and see that you found your marriage certificate. Sounds like you are on your way. The next year is going to be a busy year for you, but you can handle it.
Some day, you will stumble across information about the ow and it will not matter one hoot to you. Sometimes, God doesn't put all of the information in our laps until we are well on on way w/our own lives, separate from the mlcers.
Yes, you are far better than the ow because you believe in the scared marriage vows and honored them throughout the entire time. You handled your situation w/dignity and grace and should be very proud of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
