I resorted to deleting my own facebook account completely! It works like a charm... I don't know what he's up to and he doesn't know what I'm feeling. I also used to spend at least an hour a day on facebook (So bad, I know).
So by deleting my own facebook account, I achieved two things.
1. I stopped knowing what he's up to. I don't have to feel worried and angry when he post a picture with another girl, or spend hours analyzing what his status really means
2. I stopped wasting time on facebook and instead, focus on working on myself
Although I have missed some important events, (such as a friends' wedding!), I still think my sanity is worth it. If my friends really want me to attend their events and catch up, I'm still reachable via text and email
I feel a lot better after kicking the facebook habit.
