I think I owe you an apology for an assumption on my part...
I was assuming the reason he is writing her is not to keep in touch, but to make an effort for a concrete ending?
If this is not the case, sorry I created any confusion.
But I will stand on my own words that jealousy in any shape or form isn't a healthy response to dealing with fears. He's either going to be faithful or he isn't, and no display from you is going to change things.
I do agree that 3 is a crowd and that there needs to be some understanding between you on what types of people are allowed to be friends to BOTH of you.
On the other side of the coin, acting AS IF you are going to be okay with whatever he decides to do can only help if he's just digging his heels in to show you that you aren't the boss of him.
Again, I'm sorry for the ASSumption...
Hugs,
Betsey
