Accomplishing your goals and being where you want to be in life first is far more important than being in a relationship.
Most relationships fail because one of the partners isn't happy with themselves, if not both.
Most relationships in today's society are pretty much built around lust. Without sex, most people wouldn't be happy in that relationship, and would cheat or leave. When I truly loved a person, I could never have any form of sex with them, and yet I'd still be with them until we are no longer here on earth.
Relationships can wait. Your goals in life can't.
