What's wrong with my boyfriend's fb account? URGENT!?

[Sanjana Sarah]

This has been happening since yesterday from 1pm and is still going on till now. My boyfriend is coming online and going offline every 2 mins i guess continuously! I thought he went nuts but it isn't him . It's his account that has gone crazy! I sent him more than 20 msgs but still he hasn't replied me. I asked one of my friends abt it, he said that it is a fb virus. Are there anyways to solve this crazy thing? Any explanations to why and how this is happening? plsss... it's an emergency!
I read few of the answers below. here r sum more details: he DOES'NT have a moblie! And he is my boyfriend. I've been loving him for more than a year. But i am NOT his girlfriend! He doesn't have any girl friends either as he is very studious and quite a nerd! So, i am his only friend among the girls. I don't have his landline number too. I just need to know why his account is behaving this way. Fb is the only way I can contact him. :/
