Re: They keep calling like crazy: Will it lose attraction?
Talking on the phone is OKAY, but you need to limit it. You need to try setting up meets with them. Just flat out tell them you like talking on the phone, but its required you see them in real life too, if they just want to constantly chat on the phone they have their girlfriends for that.
If you do give them that last little bit about "they have their girlfriends for that", they will get mad and call you an asshole. Don't back down and hold your frame. "You are not an asshole, you just don't care to put that much time and energy talking to a girl who you never see"
Good luck man
DISCLAIMER: You may loose them with this one, so be prepared. It will surely piss them off a bit, but in my experience they get over it
