First of all, don't ever question yourself or think that you are boring in comparison to someone else. You're not, you just have your own way of doing things and you're living your life as you see fit. He's not better or more interesting than you. Second, it's natural for us to always question people's motives. We don not have the ability to detect their intentions and I don't know about you but not having this ability, has always left me vulnerable to people who seek to take advantage. If he wants to be friends again, that's great but if you get too uncomfortable, trust your instincts. Always trust your gut.
