Pisces and mixed signals

Hello this is my first message

So i met a very complicated pisces, im a gemini woman and im very good with people but i just cant get him he doesnt want relationships but since we started talking he changed a lot he keeps sending mixed signals if he opens up a little the next day he completely shuts me out we are friends but not the normal friend its so obvious and im a complete mess trying to figure him out, all our mutual friends keep telling me he is different around me and i can tell so the he talks and acts around me is different, im giving attention but not too much attention and when he shuts me out i would send a text just to check on him

Other thing he doesnt show our friendship like others for example if he ever takes a picture if us he would just save it like everything i send him on snapchat but would never post it as a story

Sorry for the long message but im a complete mess here pmease help

How old are u guys ?
