Alright Yuki, I'm not to vet only been married for 3 and half years, but it seems that your wife sees how close the two of you are. And with her not getting you a present or a party maybe just maybe she's pissed with herself and your receiving the backlash(this sucks I get it quite a bit). I know spending all night in a hospital on your bday sucks, but just think she was there for her friend that just had a baby. And you did let your wife know it wasn't a big deal. So she may have thought to herself that maybe the gift and party would be able to slide since that's what you said. Anyways I think communication might be key here, I know you were hyped about your party and gift, but just try and talk with her let her know that its OK. Don't even bring up your bosses gift unless she does. Make it about her, concentrate the conversation on how she's feeling. You will figure out what she's mad about when she starts opening up. And last but not least after attempts to communicate, back off just give her space to breath maybe talking to your boss about other things should then work should be placed on hold, just explain to your boss that this is a patching time...no need to add more tender to the flame. Hope this helps bud
