I'm going to choose school over my boyfriend
Why would you want to choose school over your boyfriend?
It is just logical, learning lasts forever some relationships are temporary.
It is good to make priorities in your life. You should be honest with the other person if you intend to break up with them.
I don't see why I would have to tell him. It's not like the relationship is going to last.
I respect that you want to choose school over your relationship, but you really should tell your boyfriend. You would basically be dragging him along and wasting his time when you've basically decided the relationship is over. Do him a favor and let him go.
