Well from the sounds of it, for whatever reason, he wanted to keep some things a secret, I really don't know what his motives would be, but unfortunately sometimes those things happen in life. While it sucks a whole lot and you feel very hurt by it, the only thing you can do is move on. He sounds a bit sneaky honestly, if all that you said was true about the ring and dress. That's a bit strange on his part! It probably is best to just move on if he's being that sneaky about things. A guy like that is going to end up found out by everyone and it'll come back to bite him in the butt. Better to find out now before it causes you even more grief down the road I guess.
