Feeling torn between family and my future

Hello everyone,

This is my first time posting here, so please excuse me if I make any mistakes. I’m 23F and my boyfriend is 23M. We both recently got accepted into the same university for our master’s degree. I am really, really happy about that.

But for the last two months, something has been bothering me a lot. I will have to take a loan of around $40k for my studies. Between my 2 years of MS and then working for 5-6 years to repay the loan and save some money, I feel scared about how much time I’ll be away from home.

I love my family very much( my mom, dad, brother, and my dog). Whenever I think about leaving, I start crying. My parents will be over 60 by then, my brother will also leave for college, and my parents will be alone and when i think about my dog getting older and not being there by the time I am back, I can't stop the tears from coming. If I decide to stay back and not do my master’s, I feel equally broken thinking about my boyfriend being alone in another country without me. I trust him completely, so it’s not about trust issues. We were once in a long-distance relationship in two different countries, and it was very hard on both of us. We cried almost every day, and it affected our mental health badly. I will miss him very badly, i can't afford that.

I know this sound very stupid, and not even important, but I feel torn between two things I love the most, my family, my boyfriend. my career. If I go abroad, I probably won’t be able to come home properly for 7–8 years. If I stay back, I don’t know how I’ll handle being away from him.

I know this may not sound like a huge problem, but it has been eating me up inside. Thank you for reading. I would really appreciate any advice.

( I know I am being greedy and hoping to get the best of everything, I am sorry guys :/
But thanks for taking out your time to read! )
