Ugghhh

So me and my boyfriend have been dating for a month i’m 14 and he’s turning 18 in October we’ve been close since we before i can remember and our family’s have known eachother for even longer. Neither of our parents know and I knew he had trust issues because of his ex but i didn’t think they were this bad! He doesn’t allow me to have guys on my snap which i’m fine with because before he said that “I don’t have girls on my snap, so fair is fair” which i was completely fine with but I have 1 bestfriend and it’s a guy. He knows that that’s my only bestfriend and only person i feel like i can talk to other then him. And we were hanging out and we were watching netflix off of my phone and it was connected to his tv and my guy bsf texts my number and he went off like dude. If he’s the only person I feel like i can talk to other then you how do you think he feels like. and my friend has a girlfriend and lives in Nebraska (i live in Tn)! what should i do??? *also don’t come for him and be like “he’s lying to you” i have his password to all of his socials and he has mine to all of mine*
