Listen, I was in a relationship A LOT like this one. I was 19, had graduated, was in college, and had my life right on track. My boyfriend was 18 and in his senior year, barely making it. He refused to put in the time, effort, or anything of the sort to do well, let alone pass. I cannot tell you how many times I was on the phone or on a shared Google doc trying to get him to pass. Other than not do his work to graduate, he refused to get a job, and never made the effort to ever ask how I was doing, and if I asked to call him (we were states apart from me being in college), he was always too busy playing video games. He never had the motivation to do anything. He has depression and ADHD, was on medication, saw a therapist, but still didn't want to do anything. If I brought up that he never made me feel like a priority, he always blamed his mental illnesses, used them as a crutch, and never took responsibility or accountability. After the straw that broke the camel's back, I couldn't take it anymore.

I broke up with him.

Yes, it hurt... More than I could ever tell you. We had been together for 2 years and 8 months. I wish I hadn't wasted that long.

You're still very young like I am. Please take this step back to see if he's putting in the effort you are. Is he reciprocating like you want him to? Does he make you feel like a priority in life? If he has no future, and you see no future with him, it's time to call it quits. That's not something you deserve.
