It's just your hormones rant!!

Long story short, my SO and I had plan to take our blended family to Disney 2018, he's out of the country visiting family with his child, I stayed back because I'm pregnant and where he is they say it's like smoking 7 packs a day with how nasty the air is. Well he tells me today that they are taking his child to Disney there, and that really upsets me, because the weeks we don't have his child, I don't let us and my child go do super fun exciting things, because it's not fair. And he said the only reason I'm upset is because my hormones.. I'm so sick of when I have feelings it's only because my hormones. Like no shit I'm growing a human, but surprise I can still have genuine feelings that have nothing to do with pregnancy!! That really gets me upset. My feels are valid even if I'm pregnant...sorry if this doesn't make sense I'm just frustrated with him and that situation and then his turning it around on My hormones. When I'm upset because I don't feel like he is thinking about my child, and how I try to always make sure things are fair between them.
