<human>: I've been dating a guy for over two years now and we're really close.  We both put a high value on honesty and sharing.  Lately, however, I feel like he hasn't been sharing things with me.  We've been doing long-distance for a while now, but that never affected things before, so I don't think that's the reason for it.  I talked to him about it and all he says to me is that he cares about sharing too.  I'm beginning to think that I'm just expecting too much from him.  I'm wondering how much should be shared with your SO.  I feel like we used to share so much and I just don't know what changed, if anything.

Can you condense the text into three sentences or less?
<bot>: my boyfriend isn't sharing as much with me as he used to.  How much should a person share with their SO?
