I'm sorry to hear you're so down. As everyone else seems to agree, it's perfectly natural to want to be loved and taken care of emotionally. Back here at home (away from Uni for the summer), I really start to realize how emotionally desolate and how devoid of nurturance this environment is.
As for your husband, I don't think are "wired" (in a biological sense) drastically differently than women; rather, Western society in general seems to discourage the expression of emotions from men, so you could say men are "programmed" differently. It's not the hardware that's too blame, but rather the software. (Gender Studies is one of my majors, and that which I intend to pursue in graduate school in a bit over a year, so sorry if this sounds preachy

). I'm glad to hear that your son is more openly affectionate, though.
Will you be able to see your daughter before she goes to Uni? It's tough fighting with those closest to us, but maybe the time apart will be beneficial to your relationship.
I hope you're feeling bit better.
Take care,
J
