Communication is key to saving any relationship. That and laughter. Also acts of kindness, example: "I bought you flowers today; just because it's Tuesday." Stuff like that and you should be fine. If not, hire a private eye to make sure someone is being faithful and not just trying to drive you away to be with them. Sorry that someone so nice and charming has fallen down the hole of terminated souls; I pray that you both can get out of this in one piece. But hope seems to be on your side; NEVER lose hope. My friend.
