Confused 🥴

So i was a dumb dumb kid and ever since 14 I was naive enough to let guys use me for years and I thought it was love. So it’s safe to say I’m not sure how to feel when I’m actually loved it’s all different and I’m having trouble getting used to it. Last year I let my bf move in with me we celebrated holidays together ate dinner together we acted like a married couple even though we were both in high school. Shortly after his birthday he cheats on me with a freshman while living in my house. I’ve been single for a year and am so hurt I don’t believe in relationships loving is hard for me. Over this last year I have plenty of guys to fill the void I didn’t think I had until now. A nice guy and I are dating he calls me beautiful checks in on me he’s also clingy but overly clingy he is good for me but I don’t know how to handle it. I feel like it’s fake or maybe still after a year I’m not ready a part of me doesn’t know how to feel either. I’m so confused even though I shouldn’t be...advice ?
