Hey man

I was in a long-distance relationship..it doesn't work. If she says it will not work, it means she's breaking up with you.

Problem with these relationships is you never get to see each other, you grow apart, you meet other people and life changes.

At the end of the day, it's a better decision for both of you. And if she doesn't want to anymore...you've got to let her go.
Good luck
