I’m (17m) completely lost in my dating life.

I’m a 17 year old male, and quite honestly I’ve never rlly dated someone. I’ve had some quick flings and I’ve even lost my virginity. But I’ve never been in a real relationship. I so badly want to be in one tho. I’m not sure whether it’s my looks or my personality, but I couldn’t land a girl to save my life. I tend to overthink things, ALOT. And that really doesn’t help my case. The last girl I had a “thing” with, was a 15 year old girl. We ended never dating because of the age gap. And now she’s trying to hit me up again. But I think that she is just hitting up every boy in her phone. Idk it’s all just wack. I rlly want a caring relationship, but for me that’s like impossible. And whenever things don’t work out with one girl, I always start to think of the 15 year old. And I simp for her… anyone else struggle with this?
