Need marriage advice

JTJKH
I posted a couple weeks ago about my husband not telling me happy bday then also signing up to teach a class that night which was voluntary. Well I never got a makeup dinner, no card, no I'm sorry...nothing 
Hes since then gone out to dinner twice with his co-workers tonight is the second time he's going to a restaurant that's very expensive but yesterday he refused to go to lunch with me and our daughter and he's turned down every invitation I've asked to go to dinner with me or as a family also. We again haven't spoken to each other today or yesterday other than when he wants something. I feel so miserable and unhappy but I know I'm not unhappily married. I feel like I do so much for him and our kids I do all the housework, take care of all of them, buy all of them stuff all the time and make them little notes/crafts special things for me to not even get recognized mostly by my husband. I just don't get it ...why don't I deserve to be special? 
Sorry for venting I don't have anyone else to talk to he completely ignores me when I try talking to him or I get told I'm worrying about stuff that isn't important.
