my partner is with his friends that are visiting him on campus ( we live semi long distance ish ), but he left me on read and viewing my story after few minutes posting it now he won’t answer my text

i have the urge to go off on him and i can’t control my thoughts without being rude and toxic and i know partners should always have space and boundaries but right now i feel abandoned and triggered that he did that and can’t keep my thoughts clear or positive, now i’m abt to have some trust issues and a tantrum moment because i hate being ignored

also, he would always say he never uses his phone w his friends but clearly he is on snapchat or instagram this whole time with them
