Girl I really like lives 3 hours away, we done everything already. lately I've been too needy on wanting to see her. She would say she's busy and ill get mad. it turned her off, she said she needed space, truley all my fault.

I kinda froze her out, and she started hitting me up again saying why don't I call her, and she likes me, but it's not a good idea for us to hook up. (Because of my neediness)

So last month we have been talking regularly, thing is she is returning to my city this summer, I bet she expects me to be all over her when she is here which would severely turn her off

I want to see her, but can't make it obvious. any tips or tricks?

Wait a week or two until she's been back (or until she contacts you; whichever comes first) then take her out for drinks. In the meantime, work on your inner game and start pursuing other women.
