<human>: Hey Reddit, I was hoping to get some advice about a problem I've been having with my SO.  

First off, we are both 22 (M & F), finishing our last year of college.  We've been together almost 6 months, and I really do adore her, aside from this one kind of weird behavioral trait.  We have very similar interests, share many mutual friends, and get along on a day-to-day basis quite well.  

The problem is that every few weeks, she gets it into her head that I don't appreciate her enough.  I'll think everything is going well, and then out of the blue, she'll accuse me of taking her for granted.  I really don't think this is the case, as I go out of my way to compliment her and say "I love you" almost every day.  

Anyways, when this happens, she'll demand that we do this "couple-building activity" where  she pretends she is dead.  She'll light some candles, play "Amazing Grace" (the song they played at my grandfather's funeral a few years back), lay in bed, and cover herself with a sheet.  Then I am supposed to kneel down and say some "last words" to her.  She gets pissed if I don't cry, sometimes withholding sex as punishment.  

I've always known that she has some self-esteem issues, but this seems a little much.  I've tried talking to her about it, but she just gets defensive and says that this activity is necessary for me to grow emotionally and our relationship to grow stronger.  I really don't know what to do.  I don't want to lose her, but I can't keep mourning her death every few weeks.  

So tell me Reddit, does this sound like normal behavior?  How can I show her that I appreciate her without doing this activity?

Can you provide a brief overview of the text?
<bot>: My girlfriend doesn't think that I appreciate her enough, so every few weeks she makes us do a couple-building activity where she pretends to be dead while I give her eulogy.
