Most Helpful Guy
I say cancel the trip. If you guys are on the verge of a break up and he is giving you mixed signals than I think the trip should be the last of your priorities. Especially if you are the one paying for it and he is telling you that he will decide after the trip if he wants to be with you or not. It is stupid for him to think he can make you gamble your hard earned money on a relationship where he's only being nice so he can use you. Break ups are hard and nobody wants to believe that they are being used, but from the sound of what you posted I believe you need to watch out from him.
