My boyfriend of 3 years proposed!

I feel like I’ve been waiting forever for him to propose and he finally did. It felt almost like I was dreaming. Not sure if any of you have experienced this after getting engaged. I actually went dress shopping today and afterwards at lunch I got a random amnesia feeling which also happened on the way back home from our trip(where he proposed) in Cancun. Our trip was magical. I’m ecstatic! Think I might just be overwhelmed with emotion. Has this ever happened to anyone else? Oh and also, what do you think of the dress pics?
