Would you be upset or drop it

Okay so I’m gonna try and make this make sense lol

I’ve been asking my fiancé if we can go to the gym every night for like the past two or three weeks. Reason being, he started going to the gym with his good buddy but he said it’s hard to work our with his buddy and they don’t really click at the gym. So I decided I’d go back to the gym with him and work out, but he always tells me “maybe we will later” and then it’s like 10 pm and he’ll say it’s too late. ANYWAYS, his best buddy is going out of town tomorrow for a work trip and called my fiancé and asked if he wanted to hang at the gym today before he goes out of town. My fiancé without hesitation was like “yeah I’ll go! What time” and then right after he got that info they hung up and he started picking his outfit out for the gym. I was just silent. He asked me why I looked annoyed and I told him it bothered me I’ve been asking him to go to the gym and he’s told me no and to top that off he’s just gonna leave me home alone tonight to go to the gym after I offered to go to his house after he was done working out. Now he’s telling me to go to the gym with him but I said I’d rather not work out with a group of guys and he told me that’s just me having a mental blockage and that if I got over that I could work out with them and not be alone at home. What do you ladies think about this situation? I’m off work in 2 hours and idk how I wanna act when I get home yet.
