Hello! I'm really sorry to hear that happened, especially reading everything you went through just to get your wedding planned and ready to go. Like other commenters, I'm glad he showed his true stripes now, rather than five-ten years down the line and you may have more problems to deal with, especially if it ends messy (ie. having kids or property together).
I fully recommend having a social net (besides your doggies, although that's a good one), and maybe getting some therapy to help deal with these tough times, and maybe even taking a break from Bermuda, if it helps your mental well being. I think all of us can agree that taking a break if you need it is better than forcing yourself to work through it if its detrimental to your health in anyway.
I hope everything gets better!
