The 8 in 208 is usually about karma, which means what is separated will come back around. If 208 is showing up during your twin flame separation, I read it as a boundary sign: 2 for the two separate paths, 0 for a clean slate, 8 for cycles that come back to yourself
That also means you’re getting back the energy you’re putting out. If you’re spending separation, bitter and resentful, that’s what the 8 brings back to you. It’s understandable to feel like this, but we still need to rise above these lower frequencies.
If you’re actually growing and becoming someone better, that’s what comes back.
