Don’t break up with her, introspect into what makes you feel that way and try to solve for the internal problem of self confidence rather than making rash decisions. Also, she can make her own decisions if she felt held back, don’t make a decision for her - usually when the mind tries to make a decision for someone else, it’s a sign of self-sabotage. Think about how much of a champion you are that she wants to be with you :) and life is long, one day you’ll become a champion in your own way. how would you feel if your gf broke up with you because “you became a champion” and “doesn’t want to hold you back” lol, it’s kinda funny when you spin it the other way around.
