Am I making something out of nothing?

Lakota

So a little back story. My fiancé started a new job as a Correctional Officer a few months back. I asked him to print out his schedule so I had it you know to plan things around the days he works. Well he got really upset for the first time I asked him to print the schedule out when he first started.

Fast forward to now. I asked him again this morning to print it out so I had it to plan things. (I just recently started physical therapy again and so far it’s looking at a month of PT) well he got upset again and we argued about it for about an hour then I got tired of it and just agreed with him for the reasons he won’t print it out. Well he told me to ask my sister to look at her Husbands schedule because he is a Correctional Officer as well and he said they work the same shift or whatever. So I asked her and she told me how to scheduling works and how to read the schedule properly and such. Well I told my fiancé that and he got pissed. He blew up on me and is beyond pissed because I still asked my sister about the schedule. I told him that he told me to ask her and he responded with, “ I thought we already went over this and made up about the schedule thing this morning. Why did you go ask her!?” Then he yelled, “I’m done. I won’t tell you my schedule or when I work. I’ll just leave and that will be that! If you’re going to call me a lier.”

And we are currently fighting as I’m typing this. I’m at my sisters since she needs a ride to work. And he’s back at the house but, am I making something out of nothing or should I just let it go and not bring up the schedule or ask him to print it out?
