Am I being sensitive?

Last night I decide to book me and my boyfriend a night away on Friday. Anyway, he said thank you and thought it was sweet, but today, he said he thinks I should cancel it and spend my money on something practical. Fair enough, but I cancelled it, told him and all he said was "oh ok".
I feel really hurt tbh because I went out of my way to do something nice for us (bare in mind I was gonna pay), and yet I feel like he's thrown it back in my face.
He then started arguing and saying he's sick and tired of all of this.. which he didn't explain what he meant.
Don't know if this matters but I'm pregnant, so im pretty vulnerable atm, and he stayed round mine a few nights ago, I got upset told him I'm scared about the pregnancy, and he said "don't you think I'm scared too".. then carried on and said "If it's gonna be like this every time I stay round I won't for the rest of the pregnancy"
I'm so so hurt by it, am I being sensitive?
Now he's not even replying to me.. I don't know what to do. I don't even know if I want this baby anymore. I'm so stuck.
Am I being sensitive?
