Answer 1

There are multiple possible interpretations according to contributors on Genius:

• The metaphorical x’s (hugs) and o’s (kisses) of the relationships haunt her, symbolizing her running away from any actually feelings developed in the process. “XO” is a common way to sign off in love letters, or if you’re gossip girl.

• Her ex’s and oh’s spark memories of a more sexual nature, which we can presume the “oh’s” to be the orgasms she gave, to whom became her “ex’s”.

• Ex’s and oh’s also lend themselves to X’s and O’s of the tic-tac-toe variety, thus reinforcing how she treats her relationships like a game.
