It wasn't me. . .yet.
Nevertheless, like everyone else has said. . .
You're young, appears unattached, and it also appears you guys didn't have any long term plans (such as marriage. . .if that were the case, then I'd play it a little different. . .such as sticking it out, and then later when you're 30-40years old, have a little fling with a beautiful lady and call it pay back. . .- wait did I just say that?) so follow through with moving on, kicking her to the curb, and meeting and dating as many women as you want.
Best of luck.
