I think I’m broken lol

So I haven’t dated anyone in a long while & I’ve stopped trying after an incident that happened a couple years ago. I tried dating again recently (couple months ago) and the guy ended up cheating on me :/ & then tried blaming it on me. I feel like I might have forgotten how to be in a relationship. I might just have really bad luck or something. Usually guys are only attracted to me for my body which makes me think that something may be wrong with my personality or maybe even my face since no guys really stick with me or look for a serious relationships with me. I mean, I’ve heard some conversations that guys have had about me & most of them say they’d just hook up with me. I’m only 17 & I know I still have a lot of time after high school to figure this shit out but it sucks ya know :/
