How do I make my boring character more interesting?

maybe her husband doesn't want to be with her anymore, so she's pushing herself to do better in her work. she's lost all enthusasim for life and pretty much has to fake it.Soon she'll realize she doesn't need a pig like him anyway (he ran off witha younger chica) and falls in love with her best friend at work. possibly make her a librariran or someone who works in a cubicle all day, or rather, a senior advisor to the ceo, something important, and she thinks her job is why he left her, and that's all she has left, so she devotes herself, maybe she falls for the ceo. idk, good luck.............. my advice, give her a history
