Looking for some perspective and strength please

[Emotions]

I have posted before, and if anyone is familiar I was in a relationship for over 7 years. Because she couldn't take living with me and my dad at the sametime anymore I had to move her In with her mom in Texas. I had to come back home for 4 months to finish work and figure out if we were meant to be. Within two months she cheated on me and is now in a new relationship. As I pleaded to move to dallas In the summer like I planned, she said she was in a new relationship and that it's not fair to dump him just to see if we work out. I'm devastated being below the totem pole than this guy, as I feel like I don't mean anything to her at the moment. She said she still loves me and isn't giving up on us, but we will see where life takes us. It is amicable at this point, and I would be nervous to move there anyway,  it I miss her terribly and wondering what I can do to eleviate the pain. Any questions or comments would help. Thank you.
