@jennie23,
What can I say Jennie, just take a chance. If you fancy him, go for it.
Just relax and see what happens and remember the old saying " there's plenty more fish in the sea".
So just casual conversation, don't throw yourself at him.
If it doesn't work out, it's not the end of the world.
Remember don't settle for second best and you don't have to marry or fall for the first guy that comes around. Shop around, live a little. Good Luck Girl.
