So me and my ex have been broken up for about a month. He broke up with me and deleted me off of all social media. So yesterday I was out getting fuel and my phone starts ringing. It was him. It rang 3 times before I answered. I said hello, heard nothing. Just silence. I could hear background noise like a tv or something. But not clear talking. Then he hung up 5 seconds into the call. I was just so confused. So I text him on whatsapp saying 'you phoned everything alright?' . Got no answer he's not read it either. If anyone has any ideas why he might of done that let me know. Just very weird. I want to text him on SMS aswell but don't know if I should or leave it?
