GUYS AND GIRLS! What does he see in me?

In his eyes, you have everything to off him. Not every guy is going to like you because of your looks. Stop looking on the outside and look on the inside. Obviously he doesn't care about all of that stuff, because if he did he wouldn't be with you. If you've had bad relationships with other guys in the past, but that doesn't mean this one with him will end bad. The past is the past. Those guys were jerks, this guy actually likes you for who you are. The 'nothing' you have to offer him, is everything he wants and everything he needs.
