Getting over him!

Hey guys! So I'm trying to get over this one guy that I've been stuck on for the longest time. I don't know what to do anymore. I've tried dating other people that I've been attracted too but it's like this one guy always comes back and the feelings get stronger for him!

I've tried everything, taking time away from social media, trying not to pay him any attention, ect! He hits me up one day then leaves me for days on end. Should I stay or should I move on. I am very in love with this boy so I don't mind that he leaves me for so long. But is it wrong that I've stayed? If you have any advice it'd be very much appreciated!
