Both love & care for each other but... she feels differently. How can I be more attractive?

I can't believe i read this whole thing. The way i see it though is she loves you, but frustrated how you both live so got out the relationship. It's nothing you should do just to change yourself so she can get back with you. If she love you then she will come back naturally. Giver her some space, and keep it at that. If she don't get back with you then move on. Last thing you want to do is chase after her cause if you have any chance then that will ruin it. Focus on yourself right now, and live your life.
