I need advice and help!

My BF of 6 months said he wanted to leave for Hawaii and I shot that down bc I didn't want him to leave me bc I wasn't comfortable with him selling everything and moving to work on an avacado farm for two months. We fought about it a lot and he promised that he would stay if he could buy a motorcycle. I said that's fine and I'll help him pay for it. Well two days ago we were facetiming and his friend said ' did you tell her yet' in the background and when I asked him he said that he was going to go to Hawaii for 2 months. Idk what to do. I didn't want him to do this and he is. Idk how I should be reacting.
