Right to be upset?

My husband and I agreed that he would leave for four months for work. Coming back in March for honeymoon then doing the one weekend a month home visits. Well today he Springs on me that yes he’ll be home for our honeymoon but then after that he’ll work the next 3 to 4 months straight and not come back. I’m currently 15 weeks pregnant, I was 11 when he left. So that means I’ll be alone throughout most of my pregnancy, being alone is an a big deal but I also have three cats, two dogs and our entire house to take care of on top of working full-time still. When I got upset by the fact that he won’t even be coming home for visits, he acted like it was so selfish because “the moneys for us.” That is and isn’t true, he plans on paying off his car and bike when he comes back Which are top priority for him. He will still have savings To help me cover taking the three-month maternity leave. But I already have money saved for that myself so it’s more so he can just get a head on his own. Which I completely understand is important but it just really sucks to hear the money is so much more motivated and then coming to see your pregnant wife the little time you get allotted. I understand it’s kind of silly to be upset because it is something we agreed to. But I also thought I would get to see him at least once a month.Is it ridiculous to be a little bit hurt by this?
