So sorry that happened to you! Good to see that a baby on the way has been a distraction though. Personally I would be very wary of his intentions here. Why break up with you just before a trip and then expect or even want to go. Mixed signals suck! It's also giving the impression that the trip meant more to him than the relationship. Take a good girl friend with you or if you are comfortable pamper yourself! You'll have way more fun without his shenanigans.
