I need your help!!!

I was dating this guy and I fell for him head over heals and then we broke up and at that time I sent a nude picture to his best friend I didn't know he was his best friend. Anyway he and I got back together the next day and since I didn't know he was his best friend, I didn't tell him later on he found out and we broke up. After that by 2 months we became friends but for a reason I don't really know, he stopped our frierndship. And again after a month we became friends again and it didn't last for long and then he again did the same thing and we stopped being friends and onr day he just started talking to my best friend and he was trying to get intimate with her but when he asked her to date him but she said no of course. Anyway I am trying to get over him since we broke up but he get really close by talking to my best friend because we tell each other everything and that will include him. Is there anyway I can do it and get over him? And is it normal that I still love him even after everything
