I'm talking about a guy I recently saw and he caught my attention. I do know him, but we don't exactly talk to each other. Just a hi or something. I used to be in a 'relationship" with this guy when we were like 14 years old, lol. But that's about it. After that we didn't keep in touch and now he's back in my life through a common friend. He has grown to be such a man and I'm really attracted to him. How do I approach him?
