What to do

At first things were great but now I just feel pushed away.  I also feel like I'm pushing and prying too much to get a response.  That is not the kind of interaction I want.  I won't waste my time reaching out and being vulnerable if there won't be any reciprocation.  It's just not a fair nor considerate relationship.  I was really interested in her but sometimes things don't work out and that's just the way it transpired.  There are plenty of other people for me to invest my time in.
