Why does she suddenly go offline?

Anonymous
I have been going out with this girl for about two months and we get along pretty good. However when we chat online she sometimes suddenly goes offline. No mention of why she has to or anything, she just goes offline. Then its about 40 to one hour till she responds.

Is she ignoring me or something. I'm really confused.

Thank you.
