He won't betray her ...
I've been friends with this guy for about five months now. We have
known each other for a while but only recently have we become really close.
About three months ago he started calling me all the time and asking
me to do stuff with him. I really like him.
The problem is he has a girl friend.
He would never cheat on her, but when ever we go out it's just the two
of us and he doesn't tell her.
He wrote in my annual "I Love you." I don't know if he likes
me or if he just likes me as a friend.
What do you think I should do?
Keep at it; sounds like you've almost persuaded him to betray his girlfriend
.. if he takes up with you, you'll be safe in the knowledge that now he's
had a little practice, he'll probably betray you much more quickly.
