Fuck it or tell him to fuck off???

Okay so I just turned 17 not too long ago and during the end of my junior year I had his fling with this boy me and him were like BEST FRIENDS and that's when he started the usual "it's okay just do it this once" or "please just let me hit it" but I was confused bc he was supposed to be my friend well he pressured me we eventually started doing things together then one day I went to work with a hickey on my neck well a friend saw it she guessed who it was from bc I had been with him like every weekend so I wanted to confide in someone so I told her almost every detail my first times in the stuff we did and she told like 3 of our other friends and they went to him about it long story short he thinks I told them he said he wasn't worried about it just that we wouldn't do anything again but he dropped me then 3 days later he's talking to that girl I first told about everything and I like grew up with this girl. Well a month and a half later we are friends again me and him not as close but she dropped him and he's Linda running back to me saying all this crap "just let me smash" "come over" bc we had never mad sex yet but I'm not sure if I should bc I was really broken hearted about him. Should I go for it and say fuck it bc I'm a senior now? Or tell him to fuck off? Pleaseee comment lemme know what you think bc I'm completely clueless
