To clear the doubt about whether we are in a relationship, I can say yes we are and I have no doubt about that. The reason why I'm insecure also cause of his care and don't care attitude. In fact I talked with him yesterday night, of course I didn't ask him about checking out the other girls thing. I asked  him if he is unsure about our relationship. And to my surprise he said "kind of" cause he not sure if I'm fully recover from my last relationship. Maybe I'm thinking too much as I'm scare to commit in this relationship. Guess I will just take it easy...
