I need your advice...

My sister and I are both in nursing school. Earlier this year she enrolled back into school after taking a 6 month break. She had enrolled into the same class as me after already taking that specific class, she did this to be in the same cohort as me. Well today she failed her pharm class, I passed. We had said We’d stay back for the other if one were to fail. So naturally that’s what I was planning on doing.

Well when I told my boyfriend he got so pissed and said I was holding our future back and it’s not fair. He’s saying since I’m gonna stay back, us getting married will be pushed back ( we were gonna get married next month). I’m really upset because I don’t know what to do.

Another thing is, after I graduate we were planning on getting our own place, my sister has her own place so she doesn’t have that to think about.

My sister said that I need to advance to the next class but I feel like if i did, she’d be upset.

Help 😭
