Boyfriend priorities everything else over me before a big exam and him leaving states

I (23F) have my Bar exam coming up soon. My boyfriend (24M) has been prioritizing everything over me. I have been beyond stressed this week since my exam is next week. We planned to hang out tonight after not hanging out for 3 nights and he is leaving back home for 2 months in 2 days and has chosen to prioritize going out and working out. We were hanging out tonight and supposed to have a sleepover and he kicked me out so he can go out. He blames me all the time and says he never goes out because of me while he went out during the day today and last night and we had tonight’s sleepover and hangout planned. He keeps record of everything and tracks the time we spend together. All he goes is complain about me. I have been crying for the past two hours because I feel so shitty and I can’t be in this headspace before my exam. He already said he is busy tomorrow leaving Monday a day before my exam that I need to be studying to talk about our future and if our relationship even has a future. I am working all summer and study for another licensure in the summer. Everything I do he has something to complain about. He keeps telling me he can’t wait to leave this state and leave for two months. When I have done nothing but mind my own business , study and be a good girlfriend. I am so hurt. I am so sick and tired of his mean and rude comments to me about me when I am putting so much effort in.
I am now beyond anxious. I can’t feel my body.

TL; DR: boyfriend not making me a priority. Stressed about a big exam for a licensure in 3 days. He leaves in 2 days. I won’t see him for two months. He knowingly choose to go out tonight knowing we won’t be spending quality time for two months. I don’t feel supported before my big exam at all. I feel like shit.
