To actually generalize sucks, some guys are more sentimental, more attatched than others, some more distant, just like with women, we're all individuals, different tastes. Some thing that women are the more emotional side, but, guys are just as bad, we just have always had the social stigmata attatched to showing it. If a guy shows emotions, he's seen as weak, some of the strongest men I've ever known have shown the love, or able to actually cry, it shows they truly care. The stoic, non emotional ones are the ones not in touch with themselves, or their partner. My ex has made me cry more than any person ever, and she loved me more because of it, it showed her that i truly cared.
don't think how it should be, feel how it is, do you feel the love? do you feel how things are? all are different, but, it's more feelings than it could ever be explained, try to convey that.
