Just let it be.......
Things will not happen quickly when we are standing over the stove waiting for the kettle to boil because we are not in control.
Sometimes things just have to be left alone without us pushing in either passive agressive ways or by contacting or snooping on the person who has pulled away.
Stop making excuses to contact the person who is making it clear by their actions or lack of actions that they are not ready to talk to us.
Look at what is driving you and your actions, fear, pure fear of having lost the person that your very actions may have driven away because you created the atmosphere of fear and that caused the pull back.
If you want respect from a person, then you must respect them if they want space, it's not easy, and it hurts but once you start to push, it will push them away...
