unless it's face to face or maybe over the phone if necessary, it's like you are chickening out (esp dumping someone-soooo lame). i'd rather have someone talk to me face to face. i don't think i've ever had that convo any other way.
i think he means....just asking out...not actual deep convo stuff.
i wouldnt think an innocent "hey you wanna do dinner on fri" hurts via phone or text.
