Sounds somewhat like Rouge and Grey Waldgrun.

To summarise; non-identical twins. Rouge is super clingy. Grey is not even remotely interested.

When he goes off and gets married she is SUPER pissed about it and swears vengence.

After about 17 years she gives up on that because she experiences personal growth during the time he was living away from Vale with his family.
