Me and this guy let’s call him josh have been doing friends with benefits. In the car he told me “ I hope you know we are doing this just as a friend thing, nothing more” I didn’t really care because I don’t like him like that. Anyways me and his friend was texting Because his friend let’s call him Kevin contacted me and I asked josh if he wants to hang out to do stuff josh said “ na we can’t I don't know it’s all on you” I asked him what does he mean by that “ you can met up with Kevin cause you want too” I was confused by this I told him “ we are just friends we aren’t going to do anything “ he said “sureee it’s not what I saw ur prob gonna do it with other guys” etc. i have a guy friend named David he’s one of my great guy friends I posted him on my story and mentioned his username, than out of nowhere josh stared following him, David has no clue who josh is and josh doesn’t know who he is he just followed him because I posted him. I was utterly lost and confused I hung out with josh today I told him “ your friend Kevin keeps texting me” josh said “ yeah ur gonna hang out with him and do something righttt?” I Told him no and that I just want to hang out as friends yet again he said “yeah sureeee” like in a sarcastic tone? Anyone knows why he is acting like this
