First of all you are 20. Go read Rational Male 1 and 2. Then some Heartiste.
Then yes - a LDR as you described works perfectly well. You run Game from Monday to Thursday fucking other girls and then her on weekends. She has to remain monogamous while you get the highly coveted experience that girls prefer in men.
But you are still young - you don't have to rush things. Such a LDR with you banging other chicks while she is away actually works pretty well and most men could live for decades together with a woman like that. So I would say - go for it!
As a matter of fact tell her to keep it that way for the next decades.
