i have huge trust issues and jealousy, a while ago me and my bf came to the understanding that i wasn't comfortable with him talking to other girls and if he is i want to know about it. i hope that doesn't sound crazy here. he told me he doesn't talk to girls but i ended up seeing him in a call with his friend and another girl. after having another whole talk about my boundaries again. i felt lied to but i let it go because he told me he barely talks to her and they've been friends. 

some time passes and i see him in another call with lots of people and a different girl. i brought it up but also just let it go. 

we are arguing about it again because i feel like he lied to me before when he said he doesn't talk to girls when he is literally in calls with them. he is acting like there's no problem at all and told me he did tell the truth he just doesn't talk to them "one on one." but that isn't what he told me before. i just want him to tell me the truth about things.

i'm so mad that he thinks i'm completely wrong to get upset about this. he isn't being the least bit understanding. 

it's makes me so suspicious of him because i really wouldn't expect him to act so defensive over something that is so blatantly wrong.(imo at least) what can i say to get through to him :/
