I have a friend, who for this I'll call Daisy, we've known each other for around a year and we've gotten pretty close and have gone out with our friends a few times, Around the last year, she got into a relationship and its been pretty good so far until yesterday when, I went out with my friends and I called to invite her she replied saying "she had to go shopping with her sister", so I tried convincing her like, "There has to be something you can do" and then after like a minuet i was like "Alright then I'll see ya later"

After 10 minuets her BF hits me up and he's like "Hey she said no right? So why'd you try to convince her?" I kinda just said "My bad, wont happen again" and he just said not to let it happen again. Genuinly why was he mad at me for just trying to convince her to hang out, wasnt just with me too, i was with a couple of friends who he knew really well. so AITAH?
