<human>: Hey reddit. 

I really feel like I am stuck in my relationship. I am a 24F and he is 25M. We have been together for 2.5 years now and for the first year and a half its been great. For the past year we have only been going downhill. This, on my part is largely to do with my studies, I am in my final year and have been extremely busy and emotional, irritable and depressed which is even an understatement. On his part, he has on multiple times threatened to hit me (never actually did) when he was angry and also constantly just leaves me for a few days when he is angry or says hurtful things to me. Now, I have tried to leave him on multiple occasions, where he used to come back, sweet talking. Now, that my studies end is approaching I cant bear the thought of leaving him because I dont have anyone else in my life right now and I am dealing with extreme pressure. My friends, are under the same pressure and also busy and my family is always away. So lately I have been relying on him for emotional support. Not only does he feel this pressure, which makes him frustrated but he started using it as leverage whenever he is angry. He will constantly urge me to come crawling back because he knows I have no one else right now. Even when I do come back and say something like "lets forget about our fights, lets just be together and not deal with any of this nonsense". He will answer with "Only until you learn to do things like this..." "I want you to behave like that..." It becomes very much where he stands in a point of high ground and its demeaning

I feel like I am trapped. I used to be a very strong person, especially within the relationship. But now I feel so weak. I know if I leave him, it will take a huge toll on my studies. However, while I am staying with him it does the same. I know that one would say, then just leave him if it is the same situation, but I feel like if I leave him, I am entirely alone. So even if he is horrible to me, I at least have someone.

I dont know what to do....

Can you provide a brief rundown of the text in within 3 sentences?
