How to discern what God wants you to do while dating.

I’m stuck, I’m talking to this girl right now and things are moving along, for context I’m 19 she’s 17, we’re getting to the point where we’re going to date once I talk to the parents. Im just confused though because I can’t find peace with it. I don’t really feel a romantic connection, I don’t think. I enjoy being around her, I’m drawn to her, I really enjoy spending time with her, I’m reasonably attracted to her ,she isn’t my “type”, But does that matter? But I’m not on fire for her or have the confidence to say, yes, this is the one. Does that come with time? Am I overthinking this? I’ve prayed for peace and guidance but I feel like I’m on my own here, I want to give it shot and see if feelings grow but I’m also scared of hurting her down the road. My dad tells me that if she was the one or if I really wanted to be with her I would be confident in it. I’m unsure, I feel guilty because I have a girl who truly cares for me and is what I’m looking for and has Godly qualities but I can’t seem to make up my mind. I’m really scared of making the wrong decision here, like losing someone who could be “the one” or pursuing the wrong one, and don’t know what to do, or if I need to wait. I do care for her and don’t want to hurt her and I don’t know if it’s fair for her to be with someone who isn’t sure if they want to be with her, I haven’t discussed any of this with her yet. For anyone saying I’m too young to date, explain why without bringing up money please. If anyone has prayers or wisdom to share I would appreciate it and need it, thank you.
