Hi Meg,
I was not familiar with your story prior to today. I read your previous posts. Very sorry for the pain you are experiencing. Breakups are ruff, especially under these circumstances. Although it seems there is no stopping your bf from walking down this blinded path, I am confident you will be better off. Imagine a life, a future, with children down the road...the heartache that would come upon further involvement with this man would only certainly increase. Maybe you will find each other again later in life, once he has decided it is a lie (if he does with any luck). Regardless, it is certainly not your fault...you can't control him. You tried to help. There is little more you can do. Now try & not allow yourself to get all depressed. Somewhere out there, I assure you, is another wonderful guy sans the heartache and grief.
