Trouble in paradise

So I normally don’t like to share any personal business about me and my hubby but I can’t help but need some advise cuz i am beyond angry. Let me start from the beginning, we’ve been together for 3 years and have a daughter who just turned 1. We live with his mom (who is phenomenal) and helps us with our daughter. I work hard and go to school while running a non profit as a volunteer. I’m also breastfeeding and barely get a full nights rest. EVER. Maybe 5 hrs most broken up in naps (on a lucky night) I’m always exhausted with a migraine! I’ve been dreaming of a vacay (like not kidding, literally dreaming) and just last week he got hired to DJ a destination wedding in a place that We’ve always said we’re gonna visit together. Santorini, Greece. Guys, I’ve been through so much in a year...from pregnancy horrors/trauma to our relationship (trust is being worked on) Anywho, he said he’ll ask the bride if there’s a wedding package deal so we can buy a ticket for me to join. She said no. The bride who is getting married is related to his best friend btw. He was hired last week because the first DJ bailed last min. All his expenses are paid. Hotel, food and airfare. The flights are $1,400 + and although finances aren’t where we need them to be...I have been saving for a year to go on a vacation! (I’m telling u, Im desperate) when the bride said No, he automatically told me about it and was extremely apologetic and shut down the whole idea immediately. He said he would make it up to me somehow. Anyway, I have the time off from work already and school doesn’t start until next week. When the fuck is a good time to go to Santorini Greece when the prices are off the chain?? Like seriously, Now right? I mean, we would literally ONLY pay for my ticket AND NEED SOME EXTRA CASH FOR THE WEEKEND. (Sry had caps locks on) lol anywho, I brought it up to him again and he shut it out down. Then the third time I tried to explain to him that it makes sense because 1) I have time off (which I never have) 2) all his expenses are paid 3) I have the money. 4) we have childcare...Only this time when I brought it up, it turned into a huge argument and he said “I don’t want to hear your sob story” extremely IN-fucking-sensitive amIright?! (Ok maybe I’m a pain in the butt by mentioning it again) but if anyone deserves to go out of the country I promise u it’s me! (And all you hard working moms out there too lol but no seriously...this man is out of the house working 24/7 so when I’m not in school/work babygirl is with ME. Not him. A lot of times I feel like I’m doing this all on my own. He has the luxury of getting up and leaving wherever, whenever when I don’t and it’s really heartbreaking that I feel like I’ve become a burden and have to resort to spilling my feelings on a blog rather then be able to communicate with him. I mean who says that “I don’t want to hear your sob story?!” I can’t help but feel worthless when he said that. I swear I feel like I have so much resentment building up. It’s like he can be a true asshole when it’s fitting. Anyway, any words of advise? I know at the end of the day it’s his business and he knows very well Iam independent. I use to travel alone & if i go, I will do my own thing & will have fun hanging out on my own... also it’s not impersonal, it’s his BFF’s cousin)...ugh (God bless you if you’ve read this far) am I over reacting? Should I be upset? What would you guys do?
