For guys only......please respond?

The reason i said guys only to answer this is coz most girls i think wud just go mad, id lie a guys viewpoint.My boyfiend and i live together and we are so so happy and love each other very much. Something bothered me the other day, there was a box of stuff i was emptying out and i found a couple of cards from his ex girlfriend from 4 years ago (who i know occasionallytalks to him on facebook) but its just chatting about stuff. they split amicably as they just wernt right 4 each other. I asked if we could tidy the stuff out (i didnt tell him id seen the cards) and he hid them behnd his back. He put them in a cupboard which ive seen contains loads of letter from his another ex. Theyre from his past, thats fine but i wish he hadnt hidden it from me. I have photos of me and my ex that are in a box but I threw my cards and stuff away from my ex parter as they didnt mean anything to me anymore. i just think its odd holding onto things that someone is professing their everlasting love for you when ur not with them anymore. what do u think?
