No, it's not weird. I mean, it is weird since apparently you started the whole deleting thing so in a way, you're just getting the treatment that you were dishing out. That said, I remember being young and how I also over-dramatized those relationships so I feel for you. However, the best thing you can do is move on. There are a gazillion guys out there who are ready to take you out if you want to date so while I can't tell you to forget about this guy, I can tell you with almost complete certainty that there are a few hundred guys who are better for you than he was.

No it is not weird. When we have someone in our life for a period of time and they leave, we miss them. Social media keeps us connected. Going your separate ways, is best if you are broken up. You will never move forward if you keep looking him on, or seeing him with other people. The delete might hurt for a little bit, but someday it won't sting as bad. Keep moving forward, keep the pictures away. Delete all emails, phone numbers, social media, etc... pretend they just don't exist. It is hard, but after a couple of weeks, it will get better... I know I have been there.
