New guy giving me snappy attitude?

Had a long day at new job. Maybe I’m highly sensitive and I needed time to decompress. Then the guy I’m talking to and going on dates with (about 6 months) calls and says can we go to the zoo this week. (The zoo is over an hour away and I’m working full time this new job taking up my whole day) I said we can go sometime soon I gotta get situated with my new hours. Then he sarcastically said “oh I know it’s gonna be a few months until I see you again.” (I don’t know if he said this cause he was feeling rejected that I didn’t wanna go to the zoo, but then I felt hurt when he said this to me because I wanna feel connection.) then my mother was talking to me at the same time he was talking so I didn’t really hear what he said so I just said “what are you having for dinner” and he sarcastically said oh nice way to change the subject. But I wasn’t trying to change the subject my brain was just overwhelmed with everyone talking and because I was trying to see what two people were saying I couldn’t really comprehend anything they were saying. I couldn’t even pull my brain cells together to tell him that. Then I was just kinda annoyed with his attitude. He said his brother wants a family and kids and he wants to be around that so his brother is upset, and then I told him to say to him that everything will work out. (He knows my ex cheated on me and his brother cheated on his wife he screwed up his life for a dumb decision and they got divorced) so he though I meant that everything was okay with me and my ex and like were talking and getting back together but then I explained how no I’m just saying that so he can encourage his brother to keep moving forward and have hope. This was the first time I felt such a snappy attitude from him and I don’t know what to think of it…

Then I just started crying and got anxious and didn’t feel well emotionally after talking.
