Brother, I would take the first approach and leave the letter for last. I got ruined by my ex in court and the more unreasonable or “making me look like a weirdo” content she could produce the better. Now, don’t go thinking law stuff, it’s the #1 breaker-upper of good s#tuff if you get me. Option A bro. Throw it all out there like your playing a board game, nice and easy. The mathematical way with process of elimination and all that is your best bet. Hit me up on messages on here when it’s said and done, I wanna hear the good news!
THEN hit her up with a letter about how great that was and all that mushy stuff. Use a little bit of progress and loving writings to keep it going. Before you know it, you will be making a special checking account to slip money into for a vacation in the Bahamas swimming with dolphins and enjoying each other. Amen to that if it works!
