I feel like my relationship is messing up with my future

To start off:
Me (21F) and my boyfriend (24M) have been dating for 5 years since high school. After a year of relationship, he had to leave to America because he was a student there and offered me to go with him and his parents. Due to some circumstances, it was better for me to leave at that time and
I did. We started living with his parents and that is kinda where everything went down the drain.

He was in school, I started working full time and his parents insisted that I pay the part of the rent which felt weird but anyway. I had to also pay for my own groceries and there was an expectation that I had to take care of my boyfriend as well.

Unfortunately, my parents cannot afford school in America and I kinda sticked to work for a while.

The relationship dynamic with my boyfriend is good and we really love each other. Even after 5 years, we experience the deepest connection and love, our views and experiences are very similar and I truly believe he is a person I want to spend my life is…. until his mom gets in between and makes another scandal about me not being “a part of family”.
My boyfriend cannot set the boundaries with her because she is also manipulating him hard. Man when I say this woman is a definition of horror, I mean it. The arguments with her would make
cry in bathroom for hours, she would ignore my presence and not talk to me for weeks and give me the hardest time every moment I didn’t do something her way.
Eventually I alienated myself from them and kinda felt like a separate figure in the household. I felt like a burden and coming home from a high stress job and having no support felt dreadful. Of course there were good and sweet moments until she would get pissed off again.

This whole situation lasted for 3 years until I got so depressed and so done that I moved out and now living with a roommate. My boyfriend is extremely upset and he wants me to apologize to his parents for leaving.

Now I am thinking: am I paying the fair price? I am on a different continent, trying to survive on my own since 18, no financial support, self esteem killed, no friends, constant stress from a crazy job(really), immigration struggles, don’t know how to build a career, boyfriend is dependent on parents and no support from them too, even though they offered me to come here. All that while my bf doesn’t have to stress about anything because his mom is doing everything for him, he is in school and living his best.

Anyway.
Right now I have an option to come back to my home country and have my family support me with everything and finally get into university. I won’t have to work, they will help me with exams and I will be able to take proper care of myself.
I am really terrified of losing my time but I am also terrified of ending relationship because I have to move on.

Right now I have an option to move back to Europe and have my family support me in every way. They want to help me with uni exams, pay my tuition and I will not have to work. I really miss my family and they don’t want me to lose any more time.
Of course I want it but the only thing that keeps me here is him. Yeah I am dumb and I love him.

No he can’t move back because of school and he doesn’t really want to.

Idk I am terrified of leaving the relationship not because of the argument but because of personal reasons.

Can someone just give me shit for being dumb please
