Am I the a hole?

So I’m 13 and my best friend is also 13 she is like my sister exactly like me and born on the same day as me and same religion I have known her for 10 years basically my whole life she is my best friend and she goes to a different school than me and she resently got into her first ever relationship with a guy she has a crush for some time now and I am so happy for her but there are some down sides like in our religion we are not allowed to date Muslims and he is Muslim and here comes the big RED FLAG MK 1st he hate me and your bf hating your best friend isn’t a good sign 2st he is the worst bf recorded in history he doesn’t talk to her at school doesn’t talk to her after school has no emotions for her claims to love her but treats her like shit call her a bitch tells her to fuck of and makes fun of her peoples accent and way more the most red flag person I have ever meet and he is one of them SLOW ASS people you have to scream in his ear 20 times for him to just say “huh?” He literally treats her like a friend not a gf made her cry about 30 times and he couldn’t care less he is really oblivious anyway onto the part if I was the a hole we were on call with me her him but then he asked if he could add his friend to the call me and her said yes but then he told me to “shut the fuck up when he joins” and I was so hurt that I didn’t talk at all and went on mute then his friend joined the call but then they both just started talking for 20 minutes not even acknowledging that me and her were on call when played games in silence she started talking but I wasn’t cause I was still upset about him telling me to stfu then I left the call she started texting me yelling about why I left Am I the a hole?
