I'm 21. Met this girl through a friend and we hung out last Saturday for the first time. We had been casually talking months prior and during this time I knew she was into me. Her boyfriend broke up with her a few weeks ago and so I took the opportunity. She came over, we had sex, and everything seems to click really well between us.

Only problem I'm finding is she snapchats me constantly throughout the day. We've had a few late night convo's and I'm realizing this probably a stupid idea to be this available to her. All I'm doing is revealing more and more about myself and killing any mysterious vibe to her I once had.

How should I proceed in this situation? I'd like to keep what we have going. She's LTR material which is what's kept her on my radar. I'm trying to prepare for her possible exit if I already kind of screwed myself, but if not, how should I change my approach?
