Yes... at the drop of a hat. It's been an issue since I've known her (12+ years). I don't think she is depressed - like I said ... its been an issue for years. It's another great catch-22 of my life. Almost on a nightly basis, she falls asleep on the sofa. If I try and wake her up to come to bed with me, it often escalates into a problem. She gets upset and angry... I get upset and offended... back and forth... However, if I leave her on the couch to come to bed when she wakes in the middle of the night, she gets offended because I didnt try to wake her. She comes to bed at 3am and is angry and wakes me asking why I left her out there. I've asked her repeatedly what I am supposed to do... only to have no answer. "I dont know... no idea... *shrug*...I wish I knew" all answers I've heard before. This is a very very sore subject in our house. I've often said that this is the only thing I'd change about her...
