Just call! Come on!! In the end it doesn't mater how you start the convo. Your goal is to leave him with a "warm fuzzy" feeling (everybody says that-No clue what it means-but it sounds good)...
Sound excited to call him, happy... You've gone totaly dark on him for so long, now you have to plant the seed sweetheart...
You'll be&do fine. Ssssssss, I hear something, was that your "voice" or mine? It wasn't speaking Greek so it must have been yours... K
