Woah, what a load you dropped on us! So far, your story had been a fairytale of love for seven years, of best friends getting together, of buying a house recently, etc. Now, we see that there had been breakups, a twice-delayed wedding, a prior marriage (same duration!), etc. These are all important aspects of the story leading to the WAH.
For your own good, be transparent on these boards, otherwise you'll get a good whipping like 25yearsmlc just gave to billman12 (mandatory reading for all of us!). Much like you got to be honest to your doctor, you will get perhaps less reassurance and validation, but more useful advice and solutions. Of course, it depends what you are looking for and perhaps right now you need to be told something specific, but friends might be better for this.
My concern is that you choose to ignore the flaws in your relationship. It seems to have happened before as you were caught by surprise and never seem to understand why he would want to leave you. It might be a mystery, it might be all in his head, but there's also a pattern on your part, no?
I'm probably not as gentle as you'd hoped, but believe me, it's with your own good in mind. It's not easy for any of us, let's hang together and get through it.
