Cying silently as I (22F) eat at a restaurant with my fianc? (24M). Am I just being unreasonable?

We were both on our phones while waiting for the food to arrive. We were discussing random things from time to time, and I remembered I have to message my friend (his SIL) about something I need to ask. He stopped using his phone, and I was still having a conversation with his SIL when suddenly he raised his tone saying who am I chatting. I respectfully said it was his SIL, and we were just chatting. He again repeated with much higher tone enough to hear by the table across us (his back turned against them, meaning they can see me directly.) They were looking at me and talking. I stopped using my phone and quietly waited for the food to arrive. None of us were talking at this point, and when I started eating, he began mumbling words about me being overreacting, how after I get home I will be writing on my diary, how annoying and dramatic I am. This is when I started crying silently, my tears kept falling while eating. I can?t see my food because my eyeglasses were full with teardrops. I?ve only eaten 1/4 of my food but lost the appetite and asked to go home. On our way home while walking, he then raised his voice saying how I made him feel embarrassed because people are looking at us. I kept silent and continued to walk, because once again, people are looking at us.
I went to his house and said sorry 5 minutes after he left mine, only to be told that he wasn?t yelling at me, that it was his normal voice and I shouldn?t be OA and dramatic because he got embarrassed by my crying.
After a total of I think 15-20 minutes of crying beside him and still hearing him say that he was not yelling at me, I felt myself shutdown. Like I wasn?t crying a while ago, my tone became normal, felt no pain at all, tears stopped all at once at thought ?fck this. Fck the drive I made while crying. Fck all these and I will just take the blame just to save myself from crying.? After that shutdown, I just agreed to whatever he said - me being disrespectful by using the phone, me crying and making him feel like the bad guy, me making it look like I?m the victim, me making him embarrassed, and me caring about what other thinks of me (he means about the ones across us, seeing me crying).
tl;dr: We were both on on our phones a while ago. He just stopped using is first, and I continued to use it. For me I wasn?t disrespecting him, but to him I did disrespect him. Please tell me if I am being unreasonable and OA and dramatic like he said. Please I want honest opinions, because I can?t sleep with this weighing me down.
