She might have married him to save the idiot's life, and they might have stayed married because they were both too chickenshit to admit they actually enjoyed the thought of a committed relationship though neither believed they would ever get one, but they were so long past that now it wasn't even funny anymore.
She genuinely enjoyed being seen as Tony's wife.
She knew it was petty, but she loved the envy in people's eyes when their eyes fell on her wedding ring.
She enjoyed being able to be possessive, and difficult, and loving, and worried, and just… she loved having the freedom to be herself, knowing that Tony was there, ready to catch her.
She enjoyed the way the team had responded to the random changes, adjusting as the well oiled machine Tony had created by giving them all a home.
