Most Helpful Guy
It could just be that now you're married, he's in a "comfort zone" where he doesn't feel it as important to do those things and that marrying you has covered those. For most guys it probably just is that they feel that marriage has spoke pretty well for them.
There could be a slight risk of a problem. If you think this may be the case, look at the rest of his personality, even interactions with other people and see if anything has changed.
Otherwise, just ask him why he isn't doing those things anymore. He won't mind you being honest if you're subtle (eg. just ask about the facebook thing initially).0THIS IS NOT RELEVANT ANYMORE
