dear friend ... i dunno why r u asking here about this issue ...??
it depends on you ..if u care about it is legal or illegal no body in qatar will ask you who is this girl you are talking to ... but if you r asking about is it allowed in the muslim and the catholic religion or not you have to go and ask someone who is experienced enough to give you the right answer...

it depends on u my friend weather u need just somebody to tell you "yes go on it is legal" or you need somebody to tell u the truth.

'n sorry for interruption
