Yes and no. Many people occasionally check their ex´s social media long after a breaking up. In this case though, it´s only been a week so ofc you´re still hung up on him and probably afraid he´s doing some moving on. It´ll take time for both of you, but I´d suggest to unfriend him etc. and really take a break untill you feel 100% okay with him being with other people. You used the term "stalking" which is already pretty self-explanatory in my opinion :)

Unfortunately it does. If you weren't hung up on him, then you wouldn't feel the need to see what he's been up to on his social media accounts. The best thing you can do now is to stop yourself from looking at them. If you keep looking it's going to make getting over him a million times harder. I know it's hard to do but it's better in the long term, trust me.
