Can he find out if I blocked him on MSN...?

yeah he can...there's this site called shout block or something...anyway...you type in your msn and password, and he will see all the people that have blocked him....I think you should just tell him how you feel...good luck...and i hope i helped =] xx

yeah. you can go on those sites where it tells you if someone has blocked you. but wen i went on it, it said my best mate blocked me but she acutally hadnt cuz i was tlking to her on msn at the exact moment! Weird huh! He could always ask his mates if you are online so yeahh

Yess, he can; well IFFF he has "Messenger Plus" which is an addon to windows live messenger. nd it has a list of contacts you have then next to it displays if she/he blocked you or if your still in their contacts

Um I don't know honestly. He's going to figure it out eventually, when you aren't online for a long time.

There are some ways which some programs will tell. Most of these are hit or miss and also tend to be virus ridden. If they really know anything about computers then they might have a chance to find out. If they dont and they try they will probably cause more harm then not.

No. Unless, someone adds you both to a group conversation. Then he will be able to see you've blocked him. Because you'll be in the conversation, but to him you will be 'offline'. Other than that, no he wouldn't know. x

It's not possible unless he asks a friend of yours whether or not you are online. There is nop way for him to find out for definite, but you will just appear offline to him and not anyone else.

Yep there is a programme called who's blocked me.

yes he can, theres a website that allows you to see who has blocked you cant remember offhand what its called but yes there is a program that does it
