Im going back to my old ways

A couple of months ago my mentor and friend told me to open up more so i did im cautious but i have minimize my wall,as an aqua and a scorp moon i tend to put thick walls and its there for a reason i dont open up easily,i use to isolate myself with music i dont give a fck what others are doing even though i care i dont let it show its hard to read me,i have a few friend but they are real to me and i can count on them i dont pursue frienship they just come at me,im lazy in messaging or calling i dissapear most of the time but when my real friends need me i come running to them,then the day when i started opening up a lot of people approach me seemingly wanted to be my friend and i let them i open up i put the effort in every possible way,to just end up with dissapointment and a pain in my chest it hurts like hell

For example: just calling or messaging me when they need me for something,i message them and they just see my msg then not replying,calling them and not answering,they just want to hangout when i am paying,they put their heart out to me and i give them advice but when its my turn they dont listen and dont give a fuck

I am so done with it im putting my wall up again if they want to be my friend or even come close to me then i wanna see the effort in them,im putting my mottto again i dont need a lot of friend i just want the real one
