My little crush is turning into love

I hate to admit it but my little crush is turning into love and I hate it but love it at the same time. After my ex and I broke up I’ve been having a hard time opening up to anyone but this boy... I just want to tell him everything and keep him around for as long as I can. He makes me feel good and shows me new things and experiences that I never thought I’d enjoy. He takes things slow but also makes it obvious he’s interested. However, I also do not want to feel the hurt I felt after my last breakup and the entire last two years we were together. I don’t want to push this new guy away but I don’t know how to just be open and not push away.
