If per rp she wasnt attracted to 80% of men you Included she isn't a changed women because now she is 30.

You are in the exact same situation you were before.

If you werent physically attractive in your 20s to her nothing will change now just because she is 30.( in the sexual department.) She will most likely still not want you sexually. It still wont change anything for you.

Even if your wildest revenge fantasy came true it still wouldn't change anything for you. You still didn't get to have sex with her in her prime and since you don't want her now (because she is post wall) you dont get to have sex with her now.
