umm are you talking a LOT!? maybe she's keepin them for memories... but uhh jus tell her you noticed her ex pics... and den figure out what ta do..
I think communication is important in a relationship. Try to let her know your feeling (must in soft way)! if not, dun cry to me....hehe....wish u good luck.
maybe she still misses her ex....and maybe he had meant a lot to her at one point in time...that it hurts to through or delete all the pix.........but u are the one she is with now....so...maybe just try to ignore it?
Agreed with ansonfong, communication is key to relationships. First, just try letting her know how you feel about it all, but don't be too direct and say something like "You really piss me off and it drives me crazy that you still have pictures of your ex-boyfriends". You may also have to give it some time after you let her know how you feel though, do NOT keep bugging her about it or else it'll just end up in arguments. Be strong and put up with it. Sometimes it takes a while to just let go of everything in the past. Although she may not like her ex anymore, she might still miss the *memories* that they had together. So only thing I think you can do is give her even better memories of you by being understanding and just make her happy all the time.
