Is it wrong to ask my girlfriend to end delete old hookups?

[Kirbi]

I'm a female and if she's your girl and is fully committed to just being with you for the duration of your relationship then she shouldn't have a problem with complying with this request. My brother currently does that to his gf (he cheats on her but family first so I'm not going to say anything... that's not my place) and the only reason why he keeps those numbers is so he has those options to cheat. Otherwise What's the point.? Just explain to her how you feel about it. Ask her why she has a problem deleting the numbers or whatever and if she has no good reason but still won't delete them then delete her. She acting questionable. People who are faithful don't need old hook ups to be part of their life anymore.
