Alright, it might be time for an intervention. While it's totally normal, post-breakup, to wear an item of your ex's clothing to keep them "close" to you, this really should not go on longer than a few weeks. It also shouldn't really occur in public because it just seems like a sort of desperate attempt prove you're dying to get back together. Seriously, Kristen, take off Robert's Orioles hat (dude isn't even from Baltimore, why is he such a fan?) and put it in a drawer -- along with his Irie T-shirt -- for safekeeping. Hopefully you'll get back together after he gets over this cheating business and you can wear them again. Although, please, perhaps give them a thorough washing?
