I'm so stupid

I let a guy make me believe that he was genuine and really into me. He told me all the things I wanted to hear, that he wanted a serious relationship and wanted to pursue only me. Then I asked if he wanted to chill at my place only for him to be too grabby, kept trying to put his hands down my jeans and top, took his dick out even tho I said no loads of times. And when I finally decided to give him a handjob cause I thought if I didn't he'd think I was frigid and leave, he just lost all interest. I've never had sex before so it was just moving too fast. But stupid me gave into pressure and gave him something anyway, even tho I didn't really want to. And now I'm left feeling stupid, used and my emotions are all over the place. I'm the stupidest girl ever for thinking he liked me and wanted me. Now I'm the one stuck in tears, second guessing everything and any trust I have left to offer in complete tatters. How could I be so stupid 😓
