I work in the same organisation with this guy but we're not in the same office. We got to know each other at a church function and started emailing, very casual stuff in the beginning. I know his wife and kid. The thing now is no day passes without either seeing or calling or emailing or YIMing. It used to be only Monday to Friday but now, even weekends, we exchange quite a lot of emails, usually general stuff, jokes, current issues etc etc. I enjoy talking to him and his friendship means a lot to me. He advises me a lot about relationships and is quite protective of me, more like a big brother.
In this day of technology, when do you know when you have crossed the line from casual friendship into a full blown affair even though you've not been intimate with the other person. (I mean, there's never been any kissing, inappropriate touching apart from the ocassional hug, no overt 'I love yous' etc etc).
Please help me out here. Have we crossed the line already?
