please help. I need to vent and need advice

Kaylyn
Today I surprised my fiancé with food at his work for lunch and he was on an early break. I seen him outside smoking a cigarette and it was a girl he was talking to. I was fine with it, but what really bothers me is he didn't even text me or talk to me on his break, he talked to her but didn't attempt to talk to me. When I drove up, I was just gonna put the food in his truck bc he looked "busy" but then when she walked away he yelled my name to come bring it to him. Am I being selfish or is there a reason for me to get mad? I know she's a coworker, and that's fine, but I know he wouldn't like it if I was standing outside talking to a guy and didn't tell him I was on a break or message him a couple times. He would be pissed. It just seems like he's putting in more effort to talk to coworkers than to talk to me. He jumps at his phone when other people text him when I'm around but when he's off work and I have to work, he doesn't reply for hours. Idk what to do. He doesn't talk about any situation that happens he just ignores me or ends up yelling at me when I address something. Help please ☹️😧is it my crazy hormones or is it something I should be upset about???? 😟😟😟😟
