I've been in a ltr with a guy that is 8 years older than me. He and i have so much in common and don't find it weird and really never think about it. He has met my firends and doesn't like them, he says they are immature. He hasn't had me meet his friends, saying its none of their business and who cares if you haven't. He also hasn't told his parents he is seeing anyone. He just says i was out with a. Should i be concerned?

but ultimately you cannot dictate the software (online or offline) that people use. i, personally, would reply that while this person is certainly welcome to maintain a contact with your address in it, you would prefer given that the contact you have with this person is strictly online, that they not list your address information in places you are not comfortable with. Your personal information is something that you choose to make available to people on an as-needed basic and subject to your level of comfort. given the nature of the friendship, you feel that your home address and telephone information is not relevant. ultimately, if this person is offended at your request, who cares they are just an online friend that probably wouldnt be your friend in 3D anyway.
