he starting to change

i know something wrong, or i don't know there's something wrong,or he make me pretended not to know that no one harmed. Of course i'm stupid always trying to trust my self that nothing needs to worry about. But my feeling smarter than my brain. Yes, he already changed. And more pain is knowing that he always hide everything. i always ask to myself  "is something wrong with me?" "have i not interasting as before?" untill "does anyone else who treats him better than me?" i don't know, he never tell me anything, but hey dude, do you forget that i am a girl?
