No need to send so man emails. Usually an invite to chat should be enough, if they are interested then they will say yes. If not, then move on..
The problem with FH is the cost to the benefit. There are a lot of scammers on these sights so just keep your wits about you and you should be fine. and if you don't want to fork out the dough there are free dating sights.
Just take your time and talk to them...
