Why does it bother you that he comments on everyone else's status on Face Book except yours? You are with him and those other people aren't!
My boyfriend Ken deleted me as a relationship status /friend on Face Book. (after I had already attracted him back.) I was making a joke about it and he simply said, "I know what you are doing Mel, and you know what I am doing. Face Book is for people to keep in touch and we do that everyday, so we don't need to keep in touch through Face Book since we keep in touch by being together every day."
So Christy, that is how you need to look at it too! Stop being scared. Use LOA positively and make your relationship work with LOA. I sense that you haven't completely learned to love and accept yourself. Once you do that there is no reason to be scared. I suggest you work on that so you can get rid of those negative and limited beliefs before you manifest whatever it is you are scared of. And stop snooping and over analyzing his every action on his face book profile. It is a shame that people allow Face Book to effect their lives in a negative way (with jealousy being the main culprit,) because Face Book is really a wonderful tool to reconnect with old friends.
If everything is going so wonderfully with Du, then be grateful for that and don't allow your over analyzations and fear to spoil the closeness and happiness you have when you are with him. GET RID of that fear before it manifests itself into giving you whatever you are fearful for.
