How to breakup when you’re emotionally dependent?

Me and my boyfriend are both 20 and we’ve been together for over almost a year but we were best friends first.

We were great friends but we aren’t the best lovers, we are just two different people and we argue ALOT. The arguments are draining me and I’m tired. He’s an AMAZING person but I can’t continue this. I’m starting to suffer emotionally, mentally and academically, which is especially hard for me, my damn near perfect GPA took a small hit this semester.

To make matters worse we are incredibly emotionally dependent on one another because we eat together/study together/text and talk 24/7. He even made his schedule so that we got out of class at the same time. He tells me all the time I’m the only thing that makes him happy. He’s not the only thing that makes me happy but he’s essentially my best friend right now. So breaking up would really mean starting over.

It’s so hard for me because idk who I would study with, who I would eat with. Idek how I would spend my weekends if he wasn’t with me.

At the same time I really want to get out of this relationship. It’s just really tough and I need REAL advice not just “you got this girl!” if possible.

Have any of y’all ever dealt with this and what did you do?

I just start feeling bad b/c he’s going through a lot... idk
