I met my boyfriend 2 years ago over the internet. Just by chance really. We secretly dated for about 5 months, I was in Ireland and he was in the UK. After 5 months I moved to the UK to be with him and we both came back to Ireland a few months back and we live here together now.
I didn't tell anyone that I met him online. His friends and family know we met online and they are cool with it, I however, know how my family would have responded. So I told them we met in a bar. They still don't know how we met and it shouldn't matter so I will never tell them. I don't see the point.
Some people just aren't as open minded as others. I personally think meeting someone online is far better than meeting them drunk in a bar. At least you get to know someone first before even setting your sights on them, that way personal appearances tend not to come into play.
If you want your parents to know you met someone just tell them you met him through a friend. Sometimes what they don't know won't worry them. I know if my parents knew that myself and my boyfriend met in the internet they wouldn't take our relationship seriously. If you do think they will take it well then tell them, if not, fib about it now and we they get to know your current boyfriend a bit better, tell them then. If you want. :-)
