How can I stop being so damn jealous?

So yeah this is a weird one. Classic story of meet someone and I rush things so she backs off but we decide to keep as friends since we're part of this friend group but part of me held onto that idea of us dating properly one day.

Now i can't stop overthinking that she's got someone over or she's seeing someone else, I want her to be happy but I just can't stop being jealous.
