okay. time to get personal. i've got a question for anyone, but first some background info.
there is this girl i dated for over 6 yrs. that works with my roommate (for @ 4 yrs). we all get along okay, but they are closer now that me and her are broken up. weird thing is, he has started collecting tidbits of her around our house. on our fridge are a dozen pictures of her including one of her at the beach, her dancing on a bar, and a party where he was kissing her cheek. he also bought several pieces of her art including a painting of me she made years ago eating coco puffs in my underwear. and there's also the 3'X3' portrait of her hanging in the living room. i'm pretty sure he's not hooking up with her, he just adores her. they both have signifigant others (yeah, i know, like that matters) but i still can't help but wonder what's up. i just don't think it's cool. it breaks one of the several unspoken mancodes. so my question is,
is that cool or uncool; should i say something?
