Am I Wrong..Honestly?

Today my boyfriend and I decided to workout so we can get In shape, as we're both overweight. I asked him to take pictures of me and send them to me via text message. He was complaining about it but after asking a few times he took the pics and commenced to sending them. Next thing I know he started cursing.. and said he accidentally sent the pics to his friend ( a other dude). I know it was an accident but I was SO upset. i felt humiliated...I'm so chubby, I hardly want my bf to see me with just my underwear on let alone his friend. I felt that he was being sloppy and not being careful when sending the pics because he didbt want to. I just felt horrified. HIs friend texted him back something and I asked my bf what was said via text. He read it to me but wouldn't let me see for myself..he said I should just trust him. Hes known to lie so I wanted to see for myself what they were talking about via text but he flat out refused to let me see his phone which made me feel like there was something said that he was not telling me. We ended up getting into a 2 hr arguement and I decided I wasnt going to take him or his father to work if he continued to lie to me, they would have to make their own way by calling an uber. I get tired of doing for them and its SO stressful doing almost everything by myself. I just want to be able to trust him and I know it was childish but I didnt take them to work... they made their own way. It turns out he wasnt lying in this situation when he finally let me see the texts. He said he was just testing me so he could "see what type of woman u was"....I felt bad for not picking them up from work when he wasnt lying but I dont feel bad for getting mad... I feel everything could have been avoided by just letting me see what was said about my pictures between the two of them because I was humiliated about the situation. But I also shouldn't have flipped out, I was just super embarrassed about it. What do yall think....?
