my boyfriend has been complaining that im no fun anymore. he says im more tired, and slow, and i joke less and laugh less and play less. i feel pretty much the same, maybe more tired overall. but i dont feel drastically different than my usual self. is it possible he's noticing a difference in me that i cant see? or is he maybe exaggerating small changes in my mood like me being more tired? i really dont know what to do when someone tells me im being less fun...
