WANTS TO ADD MY EX BACK ON FACEBOOK. GOOD OR BAD?

Me and my ex broke up 5 mos ago, i couldnt bear seeing his name appearing on my fb feeds and everytime i tried to contact him he's just cold and never gives me good responses, so i decided to delete him so i can move on. yes iw ould say itw as effective im feeling better now tho i still curious of what he's been up to. i stalk on him using an account of one of our mutual friends. right now i moved to the city where he used to live, and i got the feeling of adding him back simply because i just feel fine now, well maybe not totally fine i feel better. i have the feeling that i am now capable of putting things from the past, friend him again fb then continue living my life. HOWEVER, i a little worried with the thought of what he is going to think about it, or if he;s gonna approve it or not, well i really dont care on this part tho, im a lil concern of his thoughts about me adding him back and me living in his city currently. oh well, i guess i need some opinions, cant really point out my reason why iw ant to add him back, its just that i feel FINE WITH IT. plesae guys, speeak out. :) good day!
