I feel for my online ex his friend 😳 [I Miss Someone I Shouldn't]

We never met just dating over the phone text and someone video chat we played online on the PS4 ive met a few of his friends on the PS4 not in person just through party chats we hear eachother voices, well my feelings fade a way I left him because he was going set me up for something if I met him in person I over heard him through the phone he didn’t know I found out we slept through the phone , any who after the breakup his friend keep in touch we met him at the same time but I stop playing online games with his friend I was crushing on because my feelings plus I didn’t want nothing to happen I can avoid the feelings if I stop hanging over gaming plus idk if he was part that set up that I over heard 😔 how can someone set someone up with drugs for no reason knowing I am a good person and never cheated evil my ex is
Hope I didn’t confused anyone
